Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611162, here are decompositions:

61 + 31611101 = 31611162
73 + 31611089 = 31611162
113 + 31611049 = 31611162
139 + 31611023 = 31611162
151 + 31611011 = 31611162
251 + 31610911 = 31611162
269 + 31610893 = 31611162
383 + 31610779 = 31611162

Showing the first eight; more decompositions exist.
