Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611852, here are decompositions:

11 + 31611841 = 31611852
23 + 31611829 = 31611852
149 + 31611703 = 31611852
179 + 31611673 = 31611852
193 + 31611659 = 31611852
211 + 31611641 = 31611852
269 + 31611583 = 31611852
271 + 31611581 = 31611852

Showing the first eight; more decompositions exist.
