Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611308, here are decompositions:

7 + 31611301 = 31611308
37 + 31611271 = 31611308
181 + 31611127 = 31611308
241 + 31611067 = 31611308
271 + 31611037 = 31611308
397 + 31610911 = 31611308
601 + 31610707 = 31611308
727 + 31610581 = 31611308

Showing the first eight; more decompositions exist.
