Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465522, here are decompositions:

41 + 31465481 = 31465522
71 + 31465451 = 31465522
131 + 31465391 = 31465522
233 + 31465289 = 31465522
461 + 31465061 = 31465522
701 + 31464821 = 31465522
821 + 31464701 = 31465522
941 + 31464581 = 31465522

Showing the first eight; more decompositions exist.
