Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473056, here are decompositions:

19 + 31473037 = 31473056
73 + 31472983 = 31473056
127 + 31472929 = 31473056
229 + 31472827 = 31473056
283 + 31472773 = 31473056
577 + 31472479 = 31473056
607 + 31472449 = 31473056
619 + 31472437 = 31473056

Showing the first eight; more decompositions exist.
