Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537646, here are decompositions:

37 + 31537609 = 31537646
43 + 31537603 = 31537646
73 + 31537573 = 31537646
103 + 31537543 = 31537646
139 + 31537507 = 31537646
307 + 31537339 = 31537646
337 + 31537309 = 31537646
373 + 31537273 = 31537646

Showing the first eight; more decompositions exist.
