Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551078, here are decompositions:

19 + 551059 = 551078
61 + 551017 = 551078
109 + 550969 = 551078
127 + 550951 = 551078
139 + 550939 = 551078
277 + 550801 = 551078
421 + 550657 = 551078
457 + 550621 = 551078

Showing the first eight; more decompositions exist.
