Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550420, here are decompositions:

41 + 550379 = 550420
83 + 550337 = 550420
131 + 550289 = 550420
137 + 550283 = 550420
179 + 550241 = 550420
239 + 550181 = 550420
251 + 550169 = 550420
257 + 550163 = 550420

Showing the first eight; more decompositions exist.
