Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468756, here are decompositions:

29 + 31468727 = 31468756
89 + 31468667 = 31468756
167 + 31468589 = 31468756
197 + 31468559 = 31468756
227 + 31468529 = 31468756
233 + 31468523 = 31468756
239 + 31468517 = 31468756
257 + 31468499 = 31468756

Showing the first eight; more decompositions exist.
