Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492698, here are decompositions:

7 + 31492691 = 31492698
31 + 31492667 = 31492698
47 + 31492651 = 31492698
71 + 31492627 = 31492698
101 + 31492597 = 31492698
131 + 31492567 = 31492698
157 + 31492541 = 31492698
227 + 31492471 = 31492698

Showing the first eight; more decompositions exist.
