Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551454, here are decompositions:

11 + 551443 = 551454
31 + 551423 = 551454
47 + 551407 = 551454
67 + 551387 = 551454
73 + 551381 = 551454
107 + 551347 = 551454
157 + 551297 = 551454
173 + 551281 = 551454

Showing the first eight; more decompositions exist.
