Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492898, here are decompositions:

61 + 31492837 = 31492898
97 + 31492801 = 31492898
127 + 31492771 = 31492898
271 + 31492627 = 31492898
331 + 31492567 = 31492898
421 + 31492477 = 31492898
499 + 31492399 = 31492898
1171 + 31491727 = 31492898

Showing the first eight; more decompositions exist.
