Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537862, here are decompositions:

3 + 31537859 = 31537862
19 + 31537843 = 31537862
271 + 31537591 = 31537862
523 + 31537339 = 31537862
619 + 31537243 = 31537862
661 + 31537201 = 31537862
709 + 31537153 = 31537862
823 + 31537039 = 31537862

Showing the first eight; more decompositions exist.
