Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606426, here are decompositions:

3 + 31606423 = 31606426
29 + 31606397 = 31606426
53 + 31606373 = 31606426
83 + 31606343 = 31606426
107 + 31606319 = 31606426
113 + 31606313 = 31606426
149 + 31606277 = 31606426
239 + 31606187 = 31606426

Showing the first eight; more decompositions exist.
