Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537892, here are decompositions:

3 + 31537889 = 31537892
31 + 31537861 = 31537892
151 + 31537741 = 31537892
283 + 31537609 = 31537892
349 + 31537543 = 31537892
619 + 31537273 = 31537892
691 + 31537201 = 31537892
739 + 31537153 = 31537892

Showing the first eight; more decompositions exist.
