Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550390, here are decompositions:

11 + 550379 = 550390
53 + 550337 = 550390
101 + 550289 = 550390
107 + 550283 = 550390
149 + 550241 = 550390
179 + 550211 = 550390
227 + 550163 = 550390
251 + 550139 = 550390

Showing the first eight; more decompositions exist.
