Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492484, here are decompositions:

7 + 31492477 = 31492484
13 + 31492471 = 31492484
31 + 31492453 = 31492484
61 + 31492423 = 31492484
223 + 31492261 = 31492484
241 + 31492243 = 31492484
271 + 31492213 = 31492484
433 + 31492051 = 31492484

Showing the first eight; more decompositions exist.
