+ Start with 1 prime 37330116097. Add the 3 consecutive primes starting there to get a new prime: 37330116097+37330116101+37330116149 = 111990348347. Then add the 5 consecutive primes starting from the new prime, and then 7 primes from there, and then 9, 11, 13, 15, 17, 19. This gives a prime pyramid where all sums are primes.
 1:                   37330116097 = 37330116097
 3:         37330116097 + ... + 37330116149 = 111990348347
