Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529516, here are decompositions:

37 + 31529479 = 31529516
103 + 31529413 = 31529516
157 + 31529359 = 31529516
163 + 31529353 = 31529516
349 + 31529167 = 31529516
367 + 31529149 = 31529516
409 + 31529107 = 31529516
463 + 31529053 = 31529516

Showing the first eight; more decompositions exist.
