Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567166, here are decompositions:

13 + 31567153 = 31567166
79 + 31567087 = 31567166
193 + 31566973 = 31567166
199 + 31566967 = 31567166
349 + 31566817 = 31567166
373 + 31566793 = 31567166
457 + 31566709 = 31567166
577 + 31566589 = 31567166

Showing the first eight; more decompositions exist.
