Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498756, here are decompositions:

53 + 31498703 = 31498756
197 + 31498559 = 31498756
227 + 31498529 = 31498756
239 + 31498517 = 31498756
257 + 31498499 = 31498756
293 + 31498463 = 31498756
389 + 31498367 = 31498756
449 + 31498307 = 31498756

Showing the first eight; more decompositions exist.
