Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499676, here are decompositions:

17 + 31499659 = 31499676
83 + 31499593 = 31499676
139 + 31499537 = 31499676
179 + 31499497 = 31499676
269 + 31499407 = 31499676
277 + 31499399 = 31499676
293 + 31499383 = 31499676
347 + 31499329 = 31499676

Showing the first eight; more decompositions exist.
