Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537708, here are decompositions:

17 + 31537691 = 31537708
149 + 31537559 = 31537708
227 + 31537481 = 31537708
239 + 31537469 = 31537708
317 + 31537391 = 31537708
401 + 31537307 = 31537708
479 + 31537229 = 31537708
557 + 31537151 = 31537708

Showing the first eight; more decompositions exist.
