Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473922, here are decompositions:

5 + 31473917 = 31473922
59 + 31473863 = 31473922
83 + 31473839 = 31473922
113 + 31473809 = 31473922
443 + 31473479 = 31473922
509 + 31473413 = 31473922
563 + 31473359 = 31473922
659 + 31473263 = 31473922

Showing the first eight; more decompositions exist.
