Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537334, here are decompositions:

7 + 31537327 = 31537334
61 + 31537273 = 31537334
67 + 31537267 = 31537334
181 + 31537153 = 31537334
307 + 31537027 = 31537334
331 + 31537003 = 31537334
397 + 31536937 = 31537334
463 + 31536871 = 31537334

Showing the first eight; more decompositions exist.
