Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550556, here are decompositions:

3 + 550553 = 550556
37 + 550519 = 550556
43 + 550513 = 550556
67 + 550489 = 550556
109 + 550447 = 550556
277 + 550279 = 550556
367 + 550189 = 550556
379 + 550177 = 550556

Showing the first eight; more decompositions exist.
