Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537832, here are decompositions:

223 + 31537609 = 31537832
229 + 31537603 = 31537832
241 + 31537591 = 31537832
523 + 31537309 = 31537832
631 + 31537201 = 31537832
829 + 31537003 = 31537832
1009 + 31536823 = 31537832
1039 + 31536793 = 31537832

Showing the first eight; more decompositions exist.
