Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543460, here are decompositions:

7 + 31543453 = 31543460
31 + 31543429 = 31543460
229 + 31543231 = 31543460
241 + 31543219 = 31543460
523 + 31542937 = 31543460
631 + 31542829 = 31543460
661 + 31542799 = 31543460
673 + 31542787 = 31543460

Showing the first eight; more decompositions exist.
