Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543214, here are decompositions:

7 + 31543207 = 31543214
223 + 31542991 = 31543214
271 + 31542943 = 31543214
277 + 31542937 = 31543214
337 + 31542877 = 31543214
487 + 31542727 = 31543214
601 + 31542613 = 31543214
691 + 31542523 = 31543214

Showing the first eight; more decompositions exist.
