Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611066, here are decompositions:

17 + 31611049 = 31611066
23 + 31611043 = 31611066
29 + 31611037 = 31611066
37 + 31611029 = 31611066
43 + 31611023 = 31611066
173 + 31610893 = 31611066
199 + 31610867 = 31611066
293 + 31610773 = 31611066

Showing the first eight; more decompositions exist.
