Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537690, here are decompositions:

3 + 31537687 = 31537690
59 + 31537631 = 31537690
131 + 31537559 = 31537690
257 + 31537433 = 31537690
281 + 31537409 = 31537690
383 + 31537307 = 31537690
419 + 31537271 = 31537690
461 + 31537229 = 31537690

Showing the first eight; more decompositions exist.
