Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551258, here are decompositions:

61 + 551197 = 551258
79 + 551179 = 551258
151 + 551107 = 551258
199 + 551059 = 551258
241 + 551017 = 551258
307 + 550951 = 551258
349 + 550909 = 551258
397 + 550861 = 551258

Showing the first eight; more decompositions exist.
