Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537696, here are decompositions:

5 + 31537691 = 31537696
137 + 31537559 = 31537696
149 + 31537547 = 31537696
227 + 31537469 = 31537696
263 + 31537433 = 31537696
383 + 31537313 = 31537696
389 + 31537307 = 31537696
467 + 31537229 = 31537696

Showing the first eight; more decompositions exist.
