Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611910, here are decompositions:

3 + 31611907 = 31611910
17 + 31611893 = 31611910
41 + 31611869 = 31611910
59 + 31611851 = 31611910
107 + 31611803 = 31611910
149 + 31611761 = 31611910
173 + 31611737 = 31611910
191 + 31611719 = 31611910

Showing the first eight; more decompositions exist.
