Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531352, here are decompositions:

79 + 31531273 = 31531352
103 + 31531249 = 31531352
283 + 31531069 = 31531352
373 + 31530979 = 31531352
379 + 31530973 = 31531352
409 + 31530943 = 31531352
673 + 31530679 = 31531352
691 + 31530661 = 31531352

Showing the first eight; more decompositions exist.
