Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550478, here are decompositions:

7 + 550471 = 550478
31 + 550447 = 550478
37 + 550441 = 550478
109 + 550369 = 550478
127 + 550351 = 550478
199 + 550279 = 550478
211 + 550267 = 550478
349 + 550129 = 550478

Showing the first eight; more decompositions exist.
