Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605064, here are decompositions:

17 + 31605047 = 31605064
47 + 31605017 = 31605064
131 + 31604933 = 31605064
317 + 31604747 = 31605064
383 + 31604681 = 31605064
461 + 31604603 = 31605064
503 + 31604561 = 31605064
563 + 31604501 = 31605064

Showing the first eight; more decompositions exist.
