Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605052, here are decompositions:

5 + 31605047 = 31605052
23 + 31605029 = 31605052
263 + 31604789 = 31605052
293 + 31604759 = 31605052
443 + 31604609 = 31605052
449 + 31604603 = 31605052
491 + 31604561 = 31605052
599 + 31604453 = 31605052

Showing the first eight; more decompositions exist.
