Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606032, here are decompositions:

61 + 31605971 = 31606032
79 + 31605953 = 31606032
103 + 31605929 = 31606032
223 + 31605809 = 31606032
229 + 31605803 = 31606032
251 + 31605781 = 31606032
313 + 31605719 = 31606032
331 + 31605701 = 31606032

Showing the first eight; more decompositions exist.
