Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492598, here are decompositions:

31 + 31492567 = 31492598
61 + 31492537 = 31492598
127 + 31492471 = 31492598
199 + 31492399 = 31492598
229 + 31492369 = 31492598
337 + 31492261 = 31492598
547 + 31492051 = 31492598
757 + 31491841 = 31492598

Showing the first eight; more decompositions exist.
