Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465762, here are decompositions:

5 + 31465757 = 31465762
89 + 31465673 = 31465762
101 + 31465661 = 31465762
113 + 31465649 = 31465762
131 + 31465631 = 31465762
191 + 31465571 = 31465762
233 + 31465529 = 31465762
281 + 31465481 = 31465762

Showing the first eight; more decompositions exist.
