Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576822, here are decompositions:

71 + 31576751 = 31576822
83 + 31576739 = 31576822
113 + 31576709 = 31576822
149 + 31576673 = 31576822
239 + 31576583 = 31576822
281 + 31576541 = 31576822
293 + 31576529 = 31576822
311 + 31576511 = 31576822

Showing the first eight; more decompositions exist.
