Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550500, here are decompositions:

11 + 550489 = 550500
29 + 550471 = 550500
31 + 550469 = 550500
43 + 550457 = 550500
53 + 550447 = 550500
59 + 550441 = 550500
61 + 550439 = 550500
73 + 550427 = 550500

Showing the first eight; more decompositions exist.
