Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611766, here are decompositions:

5 + 31611761 = 31611766
29 + 31611737 = 31611766
47 + 31611719 = 31611766
107 + 31611659 = 31611766
149 + 31611617 = 31611766
227 + 31611539 = 31611766
239 + 31611527 = 31611766
257 + 31611509 = 31611766

Showing the first eight; more decompositions exist.
