Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606494, here are decompositions:

71 + 31606423 = 31606494
83 + 31606411 = 31606494
97 + 31606397 = 31606494
107 + 31606387 = 31606494
113 + 31606381 = 31606494
151 + 31606343 = 31606494
163 + 31606331 = 31606494
181 + 31606313 = 31606494

Showing the first eight; more decompositions exist.
