Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566464, here are decompositions:

37 + 31566427 = 31566464
67 + 31566397 = 31566464
313 + 31566151 = 31566464
421 + 31566043 = 31566464
463 + 31566001 = 31566464
547 + 31565917 = 31566464
577 + 31565887 = 31566464
613 + 31565851 = 31566464

Showing the first eight; more decompositions exist.
