Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472566, here are decompositions:

29 + 31472537 = 31472566
227 + 31472339 = 31472566
383 + 31472183 = 31472566
443 + 31472123 = 31472566
563 + 31472003 = 31472566
599 + 31471967 = 31472566
659 + 31471907 = 31472566
683 + 31471883 = 31472566

Showing the first eight; more decompositions exist.
