Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563076, here are decompositions:

3 + 31563073 = 31563076
47 + 31563029 = 31563076
89 + 31562987 = 31563076
227 + 31562849 = 31563076
449 + 31562627 = 31563076
509 + 31562567 = 31563076
557 + 31562519 = 31563076
593 + 31562483 = 31563076

Showing the first eight; more decompositions exist.
