Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547074, here are decompositions:

11 + 31547063 = 31547074
71 + 31547003 = 31547074
137 + 31546937 = 31547074
227 + 31546847 = 31547074
257 + 31546817 = 31547074
353 + 31546721 = 31547074
491 + 31546583 = 31547074
521 + 31546553 = 31547074

Showing the first eight; more decompositions exist.
