Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551126, here are decompositions:

13 + 551113 = 551126
19 + 551107 = 551126
67 + 551059 = 551126
109 + 551017 = 551126
157 + 550969 = 551126
223 + 550903 = 551126
283 + 550843 = 551126
313 + 550813 = 551126

Showing the first eight; more decompositions exist.
