Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499502, here are decompositions:

5 + 31499497 = 31499502
11 + 31499491 = 31499502
43 + 31499459 = 31499502
71 + 31499431 = 31499502
101 + 31499401 = 31499502
103 + 31499399 = 31499502
131 + 31499371 = 31499502
173 + 31499329 = 31499502

Showing the first eight; more decompositions exist.
