Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552218, here are decompositions:

127 + 552091 = 552218
307 + 551911 = 552218
409 + 551809 = 552218
487 + 551731 = 552218
547 + 551671 = 552218
631 + 551587 = 552218
661 + 551557 = 552218
757 + 551461 = 552218

Showing the first eight; more decompositions exist.
