Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493066, here are decompositions:

13 + 31493053 = 31493066
19 + 31493047 = 31493066
37 + 31493029 = 31493066
103 + 31492963 = 31493066
229 + 31492837 = 31493066
439 + 31492627 = 31493066
463 + 31492603 = 31493066
499 + 31492567 = 31493066

Showing the first eight; more decompositions exist.
