Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550388, here are decompositions:

19 + 550369 = 550388
37 + 550351 = 550388
79 + 550309 = 550388
109 + 550279 = 550388
199 + 550189 = 550388
211 + 550177 = 550388
271 + 550117 = 550388
277 + 550111 = 550388

Showing the first eight; more decompositions exist.
