Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551528, here are decompositions:

67 + 551461 = 551528
181 + 551347 = 551528
331 + 551197 = 551528
349 + 551179 = 551528
421 + 551107 = 551528
577 + 550951 = 551528
619 + 550909 = 551528
727 + 550801 = 551528

Showing the first eight; more decompositions exist.
