Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492724, here are decompositions:

61 + 31492663 = 31492724
73 + 31492651 = 31492724
97 + 31492627 = 31492724
127 + 31492597 = 31492724
157 + 31492567 = 31492724
271 + 31492453 = 31492724
331 + 31492393 = 31492724
463 + 31492261 = 31492724

Showing the first eight; more decompositions exist.
