Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511098, here are decompositions:

29 + 31511069 = 31511098
41 + 31511057 = 31511098
167 + 31510931 = 31511098
197 + 31510901 = 31511098
251 + 31510847 = 31511098
317 + 31510781 = 31511098
419 + 31510679 = 31511098
467 + 31510631 = 31511098

Showing the first eight; more decompositions exist.
