Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611336, here are decompositions:

7 + 31611329 = 31611336
13 + 31611323 = 31611336
17 + 31611319 = 31611336
37 + 31611299 = 31611336
149 + 31611187 = 31611336
173 + 31611163 = 31611336
199 + 31611137 = 31611336
223 + 31611113 = 31611336

Showing the first eight; more decompositions exist.
