Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537902, here are decompositions:

13 + 31537889 = 31537902
31 + 31537871 = 31537902
41 + 31537861 = 31537902
43 + 31537859 = 31537902
59 + 31537843 = 31537902
79 + 31537823 = 31537902
181 + 31537721 = 31537902
211 + 31537691 = 31537902

Showing the first eight; more decompositions exist.
