Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611386, here are decompositions:

7 + 31611379 = 31611386
19 + 31611367 = 31611386
67 + 31611319 = 31611386
199 + 31611187 = 31611386
223 + 31611163 = 31611386
337 + 31611049 = 31611386
349 + 31611037 = 31611386
607 + 31610779 = 31611386

Showing the first eight; more decompositions exist.
