Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551492, here are decompositions:

3 + 551489 = 551492
31 + 551461 = 551492
181 + 551311 = 551492
211 + 551281 = 551492
223 + 551269 = 551492
313 + 551179 = 551492
349 + 551143 = 551492
379 + 551113 = 551492

Showing the first eight; more decompositions exist.
