Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465682, here are decompositions:

19 + 31465663 = 31465682
103 + 31465579 = 31465682
223 + 31465459 = 31465682
373 + 31465309 = 31465682
439 + 31465243 = 31465682
499 + 31465183 = 31465682
571 + 31465111 = 31465682
613 + 31465069 = 31465682

Showing the first eight; more decompositions exist.
