Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606422, here are decompositions:

11 + 31606411 = 31606422
41 + 31606381 = 31606422
53 + 31606369 = 31606422
79 + 31606343 = 31606422
83 + 31606339 = 31606422
103 + 31606319 = 31606422
109 + 31606313 = 31606422
139 + 31606283 = 31606422

Showing the first eight; more decompositions exist.
