Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551466, here are decompositions:

5 + 551461 = 551466
23 + 551443 = 551466
43 + 551423 = 551466
59 + 551407 = 551466
79 + 551387 = 551466
103 + 551363 = 551466
127 + 551339 = 551466
197 + 551269 = 551466

Showing the first eight; more decompositions exist.
