Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551136, here are decompositions:

7 + 551129 = 551136
23 + 551113 = 551136
29 + 551107 = 551136
37 + 551099 = 551136
43 + 551093 = 551136
67 + 551069 = 551136
73 + 551063 = 551136
97 + 551039 = 551136

Showing the first eight; more decompositions exist.
