Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626064, here are decompositions:

11 + 31626053 = 31626064
23 + 31626041 = 31626064
53 + 31626011 = 31626064
83 + 31625981 = 31626064
101 + 31625963 = 31626064
257 + 31625807 = 31626064
311 + 31625753 = 31626064
383 + 31625681 = 31626064

Showing the first eight; more decompositions exist.
