Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627774, here are decompositions:

11 + 31627763 = 31627774
23 + 31627751 = 31627774
47 + 31627727 = 31627774
53 + 31627721 = 31627774
173 + 31627601 = 31627774
197 + 31627577 = 31627774
263 + 31627511 = 31627774
383 + 31627391 = 31627774

Showing the first eight; more decompositions exist.
