Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476004, here are decompositions:

41 + 31475963 = 31476004
191 + 31475813 = 31476004
227 + 31475777 = 31476004
233 + 31475771 = 31476004
617 + 31475387 = 31476004
683 + 31475321 = 31476004
761 + 31475243 = 31476004
773 + 31475231 = 31476004

Showing the first eight; more decompositions exist.
