Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550278, here are decompositions:

11 + 550267 = 550278
37 + 550241 = 550278
67 + 550211 = 550278
89 + 550189 = 550278
97 + 550181 = 550278
101 + 550177 = 550278
109 + 550169 = 550278
139 + 550139 = 550278

Showing the first eight; more decompositions exist.
