Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611326, here are decompositions:

3 + 31611323 = 31611326
7 + 31611319 = 31611326
139 + 31611187 = 31611326
163 + 31611163 = 31611326
199 + 31611127 = 31611326
277 + 31611049 = 31611326
283 + 31611043 = 31611326
433 + 31610893 = 31611326

Showing the first eight; more decompositions exist.
