Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627822, here are decompositions:

11 + 31627811 = 31627822
29 + 31627793 = 31627822
59 + 31627763 = 31627822
71 + 31627751 = 31627822
101 + 31627721 = 31627822
173 + 31627649 = 31627822
263 + 31627559 = 31627822
311 + 31627511 = 31627822

Showing the first eight; more decompositions exist.
