Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465736, here are decompositions:

73 + 31465663 = 31465736
157 + 31465579 = 31465736
277 + 31465459 = 31465736
373 + 31465363 = 31465736
607 + 31465129 = 31465736
613 + 31465123 = 31465736
733 + 31465003 = 31465736
769 + 31464967 = 31465736

Showing the first eight; more decompositions exist.
