Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465710, here are decompositions:

13 + 31465697 = 31465710
37 + 31465673 = 31465710
47 + 31465663 = 31465710
61 + 31465649 = 31465710
79 + 31465631 = 31465710
109 + 31465601 = 31465710
131 + 31465579 = 31465710
139 + 31465571 = 31465710

Showing the first eight; more decompositions exist.
