Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529936, here are decompositions:

3 + 31529933 = 31529936
13 + 31529923 = 31529936
37 + 31529899 = 31529936
307 + 31529629 = 31529936
313 + 31529623 = 31529936
379 + 31529557 = 31529936
397 + 31529539 = 31529936
457 + 31529479 = 31529936

Showing the first eight; more decompositions exist.
