Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551330, here are decompositions:

19 + 551311 = 551330
61 + 551269 = 551330
97 + 551233 = 551330
151 + 551179 = 551330
223 + 551107 = 551330
271 + 551059 = 551330
313 + 551017 = 551330
337 + 550993 = 551330

Showing the first eight; more decompositions exist.
