Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606326, here are decompositions:

7 + 31606319 = 31606326
13 + 31606313 = 31606326
29 + 31606297 = 31606326
43 + 31606283 = 31606326
47 + 31606279 = 31606326
139 + 31606187 = 31606326
229 + 31606097 = 31606326
239 + 31606087 = 31606326

Showing the first eight; more decompositions exist.
