Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520592, here are decompositions:

11 + 31520581 = 31520592
13 + 31520579 = 31520592
23 + 31520569 = 31520592
73 + 31520519 = 31520592
83 + 31520509 = 31520592
101 + 31520491 = 31520592
109 + 31520483 = 31520592
113 + 31520479 = 31520592

Showing the first eight; more decompositions exist.
