Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499566, here are decompositions:

5 + 31499561 = 31499566
29 + 31499537 = 31499566
107 + 31499459 = 31499566
167 + 31499399 = 31499566
179 + 31499387 = 31499566
239 + 31499327 = 31499566
257 + 31499309 = 31499566
269 + 31499297 = 31499566

Showing the first eight; more decompositions exist.
