Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605934, here are decompositions:

5 + 31605929 = 31605934
131 + 31605803 = 31605934
233 + 31605701 = 31605934
383 + 31605551 = 31605934
443 + 31605491 = 31605934
491 + 31605443 = 31605934
557 + 31605377 = 31605934
677 + 31605257 = 31605934

Showing the first eight; more decompositions exist.
