Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537496, here are decompositions:

19 + 31537477 = 31537496
157 + 31537339 = 31537496
223 + 31537273 = 31537496
229 + 31537267 = 31537496
349 + 31537147 = 31537496
409 + 31537087 = 31537496
457 + 31537039 = 31537496
673 + 31536823 = 31537496

Showing the first eight; more decompositions exist.
