Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551522, here are decompositions:

3 + 551519 = 551522
19 + 551503 = 551522
61 + 551461 = 551522
79 + 551443 = 551522
211 + 551311 = 551522
241 + 551281 = 551522
379 + 551143 = 551522
409 + 551113 = 551522

Showing the first eight; more decompositions exist.
