Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567544, here are decompositions:

31 + 31567513 = 31567544
277 + 31567267 = 31567544
313 + 31567231 = 31567544
331 + 31567213 = 31567544
457 + 31567087 = 31567544
571 + 31566973 = 31567544
577 + 31566967 = 31567544
643 + 31566901 = 31567544

Showing the first eight; more decompositions exist.
