Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605334, here are decompositions:

23 + 31605311 = 31605334
71 + 31605263 = 31605334
113 + 31605221 = 31605334
191 + 31605143 = 31605334
263 + 31605071 = 31605334
317 + 31605017 = 31605334
347 + 31604987 = 31605334
401 + 31604933 = 31605334

Showing the first eight; more decompositions exist.
