Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550646, here are decompositions:

37 + 550609 = 550646
127 + 550519 = 550646
157 + 550489 = 550646
199 + 550447 = 550646
277 + 550369 = 550646
337 + 550309 = 550646
367 + 550279 = 550646
379 + 550267 = 550646

Showing the first eight; more decompositions exist.
