Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611194, here are decompositions:

7 + 31611187 = 31611194
31 + 31611163 = 31611194
67 + 31611127 = 31611194
127 + 31611067 = 31611194
151 + 31611043 = 31611194
157 + 31611037 = 31611194
283 + 31610911 = 31611194
421 + 31610773 = 31611194

Showing the first eight; more decompositions exist.
