Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485074, here are decompositions:

7 + 31485067 = 31485074
43 + 31485031 = 31485074
73 + 31485001 = 31485074
163 + 31484911 = 31485074
211 + 31484863 = 31485074
277 + 31484797 = 31485074
457 + 31484617 = 31485074
541 + 31484533 = 31485074

Showing the first eight; more decompositions exist.
