Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611252, here are decompositions:

89 + 31611163 = 31611252
139 + 31611113 = 31611252
151 + 31611101 = 31611252
163 + 31611089 = 31611252
223 + 31611029 = 31611252
229 + 31611023 = 31611252
241 + 31611011 = 31611252
359 + 31610893 = 31611252

Showing the first eight; more decompositions exist.
