Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550458, here are decompositions:

11 + 550447 = 550458
17 + 550441 = 550458
19 + 550439 = 550458
31 + 550427 = 550458
79 + 550379 = 550458
89 + 550369 = 550458
107 + 550351 = 550458
149 + 550309 = 550458

Showing the first eight; more decompositions exist.
