Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550594, here are decompositions:

7 + 31550587 = 31550594
13 + 31550581 = 31550594
37 + 31550557 = 31550594
157 + 31550437 = 31550594
193 + 31550401 = 31550594
223 + 31550371 = 31550594
241 + 31550353 = 31550594
307 + 31550287 = 31550594

Showing the first eight; more decompositions exist.
