Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529336, here are decompositions:

67 + 31529269 = 31529336
79 + 31529257 = 31529336
229 + 31529107 = 31529336
283 + 31529053 = 31529336
367 + 31528969 = 31529336
523 + 31528813 = 31529336
607 + 31528729 = 31529336
613 + 31528723 = 31529336

Showing the first eight; more decompositions exist.
