Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591176, here are decompositions:

5 + 31591171 = 31591176
17 + 31591159 = 31591176
83 + 31591093 = 31591176
109 + 31591067 = 31591176
139 + 31591037 = 31591176
163 + 31591013 = 31591176
167 + 31591009 = 31591176
233 + 31590943 = 31591176

Showing the first eight; more decompositions exist.
