Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514488, here are decompositions:

11 + 31514477 = 31514488
59 + 31514429 = 31514488
179 + 31514309 = 31514488
191 + 31514297 = 31514488
197 + 31514291 = 31514488
227 + 31514261 = 31514488
521 + 31513967 = 31514488
701 + 31513787 = 31514488

Showing the first eight; more decompositions exist.
