Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566632, here are decompositions:

43 + 31566589 = 31566632
73 + 31566559 = 31566632
109 + 31566523 = 31566632
151 + 31566481 = 31566632
283 + 31566349 = 31566632
463 + 31566169 = 31566632
571 + 31566061 = 31566632
613 + 31566019 = 31566632

Showing the first eight; more decompositions exist.
