Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550466, here are decompositions:

5 + 31550461 = 31550466
7 + 31550459 = 31550466
19 + 31550447 = 31550466
29 + 31550437 = 31550466
109 + 31550357 = 31550466
113 + 31550353 = 31550466
127 + 31550339 = 31550466
137 + 31550329 = 31550466

Showing the first eight; more decompositions exist.
