Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566962, here are decompositions:

43 + 31566919 = 31566962
61 + 31566901 = 31566962
199 + 31566763 = 31566962
331 + 31566631 = 31566962
373 + 31566589 = 31566962
421 + 31566541 = 31566962
439 + 31566523 = 31566962
613 + 31566349 = 31566962

Showing the first eight; more decompositions exist.
