Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465822, here are decompositions:

41 + 31465781 = 31465822
149 + 31465673 = 31465822
173 + 31465649 = 31465822
191 + 31465631 = 31465822
251 + 31465571 = 31465822
293 + 31465529 = 31465822
431 + 31465391 = 31465822
599 + 31465223 = 31465822

Showing the first eight; more decompositions exist.
