Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563716, here are decompositions:

313 + 31563403 = 31563716
367 + 31563349 = 31563716
433 + 31563283 = 31563716
439 + 31563277 = 31563716
463 + 31563253 = 31563716
523 + 31563193 = 31563716
643 + 31563073 = 31563716
673 + 31563043 = 31563716

Showing the first eight; more decompositions exist.
