Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550534, here are decompositions:

3 + 31550531 = 31550534
73 + 31550461 = 31550534
97 + 31550437 = 31550534
163 + 31550371 = 31550534
181 + 31550353 = 31550534
277 + 31550257 = 31550534
283 + 31550251 = 31550534
313 + 31550221 = 31550534

Showing the first eight; more decompositions exist.
