Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567064, here are decompositions:

97 + 31566967 = 31567064
163 + 31566901 = 31567064
271 + 31566793 = 31567064
433 + 31566631 = 31567064
523 + 31566541 = 31567064
541 + 31566523 = 31567064
547 + 31566517 = 31567064
577 + 31566487 = 31567064

Showing the first eight; more decompositions exist.
