Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537316, here are decompositions:

3 + 31537313 = 31537316
7 + 31537309 = 31537316
43 + 31537273 = 31537316
73 + 31537243 = 31537316
163 + 31537153 = 31537316
229 + 31537087 = 31537316
277 + 31537039 = 31537316
313 + 31537003 = 31537316

Showing the first eight; more decompositions exist.
