Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563746, here are decompositions:

13 + 31563733 = 31563746
283 + 31563463 = 31563746
397 + 31563349 = 31563746
463 + 31563283 = 31563746
619 + 31563127 = 31563746
673 + 31563073 = 31563746
733 + 31563013 = 31563746
787 + 31562959 = 31563746

Showing the first eight; more decompositions exist.
