Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520962, here are decompositions:

3 + 31520959 = 31520962
101 + 31520861 = 31520962
383 + 31520579 = 31520962
443 + 31520519 = 31520962
479 + 31520483 = 31520962
509 + 31520453 = 31520962
563 + 31520399 = 31520962
569 + 31520393 = 31520962

Showing the first eight; more decompositions exist.
