Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465922, here are decompositions:

31 + 31465891 = 31465922
43 + 31465879 = 31465922
73 + 31465849 = 31465922
181 + 31465741 = 31465922
211 + 31465711 = 31465922
463 + 31465459 = 31465922
601 + 31465321 = 31465922
613 + 31465309 = 31465922

Showing the first eight; more decompositions exist.
