Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611366, here are decompositions:

37 + 31611329 = 31611366
43 + 31611323 = 31611366
47 + 31611319 = 31611366
67 + 31611299 = 31611366
179 + 31611187 = 31611366
229 + 31611137 = 31611366
239 + 31611127 = 31611366
277 + 31611089 = 31611366

Showing the first eight; more decompositions exist.
