Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606464, here are decompositions:

41 + 31606423 = 31606464
53 + 31606411 = 31606464
67 + 31606397 = 31606464
83 + 31606381 = 31606464
151 + 31606313 = 31606464
167 + 31606297 = 31606464
181 + 31606283 = 31606464
277 + 31606187 = 31606464

Showing the first eight; more decompositions exist.
