Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550468, here are decompositions:

7 + 31550461 = 31550468
31 + 31550437 = 31550468
67 + 31550401 = 31550468
97 + 31550371 = 31550468
139 + 31550329 = 31550468
181 + 31550287 = 31550468
211 + 31550257 = 31550468
331 + 31550137 = 31550468

Showing the first eight; more decompositions exist.
