Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606036, here are decompositions:

53 + 31605983 = 31606036
83 + 31605953 = 31606036
107 + 31605929 = 31606036
227 + 31605809 = 31606036
233 + 31605803 = 31606036
257 + 31605779 = 31606036
263 + 31605773 = 31606036
317 + 31605719 = 31606036

Showing the first eight; more decompositions exist.
