Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550530, here are decompositions:

11 + 550519 = 550530
17 + 550513 = 550530
41 + 550489 = 550530
59 + 550471 = 550530
61 + 550469 = 550530
73 + 550457 = 550530
83 + 550447 = 550530
89 + 550441 = 550530

Showing the first eight; more decompositions exist.
