Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550438, here are decompositions:

11 + 550427 = 550438
59 + 550379 = 550438
101 + 550337 = 550438
149 + 550289 = 550438
197 + 550241 = 550438
227 + 550211 = 550438
257 + 550181 = 550438
269 + 550169 = 550438

Showing the first eight; more decompositions exist.
