Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537286, here are decompositions:

13 + 31537273 = 31537286
19 + 31537267 = 31537286
43 + 31537243 = 31537286
139 + 31537147 = 31537286
199 + 31537087 = 31537286
283 + 31537003 = 31537286
349 + 31536937 = 31537286
439 + 31536847 = 31537286

Showing the first eight; more decompositions exist.
