Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611084, here are decompositions:

17 + 31611067 = 31611084
41 + 31611043 = 31611084
47 + 31611037 = 31611084
61 + 31611023 = 31611084
67 + 31611017 = 31611084
73 + 31611011 = 31611084
173 + 31610911 = 31611084
191 + 31610893 = 31611084

Showing the first eight; more decompositions exist.
