Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551524, here are decompositions:

5 + 551519 = 551524
41 + 551483 = 551524
101 + 551423 = 551524
137 + 551387 = 551524
227 + 551297 = 551524
293 + 551231 = 551524
317 + 551207 = 551524
431 + 551093 = 551524

Showing the first eight; more decompositions exist.
