Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493336, here are decompositions:

13 + 31493323 = 31493336
283 + 31493053 = 31493336
307 + 31493029 = 31493336
373 + 31492963 = 31493336
487 + 31492849 = 31493336
499 + 31492837 = 31493336
673 + 31492663 = 31493336
709 + 31492627 = 31493336

Showing the first eight; more decompositions exist.
