Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591182, here are decompositions:

5 + 31591177 = 31591182
11 + 31591171 = 31591182
23 + 31591159 = 31591182
41 + 31591141 = 31591182
83 + 31591099 = 31591182
89 + 31591093 = 31591182
151 + 31591031 = 31591182
173 + 31591009 = 31591182

Showing the first eight; more decompositions exist.
