Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550518, here are decompositions:

5 + 550513 = 550518
29 + 550489 = 550518
47 + 550471 = 550518
61 + 550457 = 550518
71 + 550447 = 550518
79 + 550439 = 550518
139 + 550379 = 550518
149 + 550369 = 550518

Showing the first eight; more decompositions exist.
