Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551564, here are decompositions:

7 + 551557 = 551564
61 + 551503 = 551564
103 + 551461 = 551564
157 + 551407 = 551564
283 + 551281 = 551564
331 + 551233 = 551564
367 + 551197 = 551564
421 + 551143 = 551564

Showing the first eight; more decompositions exist.
