Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499414, here are decompositions:

3 + 31499411 = 31499414
7 + 31499407 = 31499414
13 + 31499401 = 31499414
31 + 31499383 = 31499414
43 + 31499371 = 31499414
73 + 31499341 = 31499414
103 + 31499311 = 31499414
277 + 31499137 = 31499414

Showing the first eight; more decompositions exist.
