Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493552, here are decompositions:

19 + 31493533 = 31493552
31 + 31493521 = 31493552
109 + 31493443 = 31493552
199 + 31493353 = 31493552
229 + 31493323 = 31493552
421 + 31493131 = 31493552
499 + 31493053 = 31493552
523 + 31493029 = 31493552

Showing the first eight; more decompositions exist.
