Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456922, here are decompositions:

19 + 31456903 = 31456922
31 + 31456891 = 31456922
73 + 31456849 = 31456922
103 + 31456819 = 31456922
181 + 31456741 = 31456922
271 + 31456651 = 31456922
283 + 31456639 = 31456922
421 + 31456501 = 31456922

Showing the first eight; more decompositions exist.
