Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537936, here are decompositions:

47 + 31537889 = 31537936
113 + 31537823 = 31537936
389 + 31537547 = 31537936
467 + 31537469 = 31537936
503 + 31537433 = 31537936
809 + 31537127 = 31537936
839 + 31537097 = 31537936
887 + 31537049 = 31537936

Showing the first eight; more decompositions exist.
