Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465706, here are decompositions:

43 + 31465663 = 31465706
127 + 31465579 = 31465706
397 + 31465309 = 31465706
463 + 31465243 = 31465706
523 + 31465183 = 31465706
577 + 31465129 = 31465706
607 + 31465099 = 31465706
673 + 31465033 = 31465706

Showing the first eight; more decompositions exist.
