Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605096, here are decompositions:

23 + 31605073 = 31605096
67 + 31605029 = 31605096
79 + 31605017 = 31605096
109 + 31604987 = 31605096
137 + 31604959 = 31605096
163 + 31604933 = 31605096
233 + 31604863 = 31605096
293 + 31604803 = 31605096

Showing the first eight; more decompositions exist.
