Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550550, here are decompositions:

19 + 550531 = 550550
31 + 550519 = 550550
37 + 550513 = 550550
61 + 550489 = 550550
79 + 550471 = 550550
103 + 550447 = 550550
109 + 550441 = 550550
181 + 550369 = 550550

Showing the first eight; more decompositions exist.
