Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492524, here are decompositions:

31 + 31492493 = 31492524
47 + 31492477 = 31492524
53 + 31492471 = 31492524
71 + 31492453 = 31492524
101 + 31492423 = 31492524
103 + 31492421 = 31492524
131 + 31492393 = 31492524
263 + 31492261 = 31492524

Showing the first eight; more decompositions exist.
