Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465496, here are decompositions:

37 + 31465459 = 31465496
79 + 31465417 = 31465496
313 + 31465183 = 31465496
367 + 31465129 = 31465496
373 + 31465123 = 31465496
397 + 31465099 = 31465496
457 + 31465039 = 31465496
463 + 31465033 = 31465496

Showing the first eight; more decompositions exist.
