Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611576, here are decompositions:

23 + 31611553 = 31611576
37 + 31611539 = 31611576
67 + 31611509 = 31611576
89 + 31611487 = 31611576
103 + 31611473 = 31611576
109 + 31611467 = 31611576
137 + 31611439 = 31611576
173 + 31611403 = 31611576

Showing the first eight; more decompositions exist.
