Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537376, here are decompositions:

37 + 31537339 = 31537376
67 + 31537309 = 31537376
103 + 31537273 = 31537376
109 + 31537267 = 31537376
223 + 31537153 = 31537376
229 + 31537147 = 31537376
337 + 31537039 = 31537376
349 + 31537027 = 31537376

Showing the first eight; more decompositions exist.
