Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472446, here are decompositions:

107 + 31472339 = 31472446
263 + 31472183 = 31472446
293 + 31472153 = 31472446
443 + 31472003 = 31472446
479 + 31471967 = 31472446
563 + 31471883 = 31472446
647 + 31471799 = 31472446
659 + 31471787 = 31472446

Showing the first eight; more decompositions exist.
