Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563064, here are decompositions:

23 + 31563041 = 31563064
83 + 31562981 = 31563064
263 + 31562801 = 31563064
353 + 31562711 = 31563064
443 + 31562621 = 31563064
461 + 31562603 = 31563064
521 + 31562543 = 31563064
563 + 31562501 = 31563064

Showing the first eight; more decompositions exist.
