Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550498, here are decompositions:

19 + 31550479 = 31550498
37 + 31550461 = 31550498
61 + 31550437 = 31550498
97 + 31550401 = 31550498
127 + 31550371 = 31550498
211 + 31550287 = 31550498
241 + 31550257 = 31550498
277 + 31550221 = 31550498

Showing the first eight; more decompositions exist.
