Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550486, here are decompositions:

17 + 550469 = 550486
29 + 550457 = 550486
47 + 550439 = 550486
59 + 550427 = 550486
107 + 550379 = 550486
149 + 550337 = 550486
197 + 550289 = 550486
317 + 550169 = 550486

Showing the first eight; more decompositions exist.
