Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492460, here are decompositions:

7 + 31492453 = 31492460
31 + 31492429 = 31492460
37 + 31492423 = 31492460
61 + 31492399 = 31492460
67 + 31492393 = 31492460
199 + 31492261 = 31492460
367 + 31492093 = 31492460
379 + 31492081 = 31492460

Showing the first eight; more decompositions exist.
