Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493304, here are decompositions:

13 + 31493291 = 31493304
53 + 31493251 = 31493304
103 + 31493201 = 31493304
113 + 31493191 = 31493304
151 + 31493153 = 31493304
173 + 31493131 = 31493304
251 + 31493053 = 31493304
257 + 31493047 = 31493304

Showing the first eight; more decompositions exist.
