Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550628, here are decompositions:

7 + 550621 = 550628
19 + 550609 = 550628
97 + 550531 = 550628
109 + 550519 = 550628
139 + 550489 = 550628
157 + 550471 = 550628
181 + 550447 = 550628
277 + 550351 = 550628

Showing the first eight; more decompositions exist.
