+ 3 + the integer formed from first 451 digits after the decimal point in π is prime. [De Geest]

+ 10451 + 451 is prime. [Gupta]

+ The largest brilliant number resulting from the sum of n consecutive odd-distinct-digit primes whose digits are in ascending order, (n=5), i.e., 37 + 59 + 79 + 137 + 139 = 451 = 11 × 41. Note that 4111, i.e., the larger concatenation of its prime factors is a near-repunit prime. [Loungrides]
