Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588806, here are decompositions:

97 + 31588709 = 31588806
107 + 31588699 = 31588806
113 + 31588693 = 31588806
127 + 31588679 = 31588806
149 + 31588657 = 31588806
163 + 31588643 = 31588806
199 + 31588607 = 31588806
283 + 31588523 = 31588806

Showing the first eight; more decompositions exist.
