Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456822, here are decompositions:

3 + 31456819 = 31456822
41 + 31456781 = 31456822
53 + 31456769 = 31456822
83 + 31456739 = 31456822
101 + 31456721 = 31456822
233 + 31456589 = 31456822
443 + 31456379 = 31456822
461 + 31456361 = 31456822

Showing the first eight; more decompositions exist.
