Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551508, here are decompositions:

5 + 551503 = 551508
19 + 551489 = 551508
47 + 551461 = 551508
101 + 551407 = 551508
127 + 551381 = 551508
197 + 551311 = 551508
211 + 551297 = 551508
227 + 551281 = 551508

Showing the first eight; more decompositions exist.
