Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550450, here are decompositions:

3 + 31550447 = 31550450
13 + 31550437 = 31550450
79 + 31550371 = 31550450
97 + 31550353 = 31550450
163 + 31550287 = 31550450
193 + 31550257 = 31550450
199 + 31550251 = 31550450
229 + 31550221 = 31550450

Showing the first eight; more decompositions exist.
