Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529564, here are decompositions:

7 + 31529557 = 31529564
13 + 31529551 = 31529564
43 + 31529521 = 31529564
151 + 31529413 = 31529564
211 + 31529353 = 31529564
307 + 31529257 = 31529564
397 + 31529167 = 31529564
457 + 31529107 = 31529564

Showing the first eight; more decompositions exist.
