Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551738, here are decompositions:

7 + 551731 = 551738
67 + 551671 = 551738
79 + 551659 = 551738
151 + 551587 = 551738
157 + 551581 = 551738
181 + 551557 = 551738
199 + 551539 = 551738
277 + 551461 = 551738

Showing the first eight; more decompositions exist.
