Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627796, here are decompositions:

3 + 31627793 = 31627796
43 + 31627753 = 31627796
157 + 31627639 = 31627796
223 + 31627573 = 31627796
229 + 31627567 = 31627796
313 + 31627483 = 31627796
439 + 31627357 = 31627796
463 + 31627333 = 31627796

Showing the first eight; more decompositions exist.
