Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550312, here are decompositions:

3 + 550309 = 550312
23 + 550289 = 550312
29 + 550283 = 550312
71 + 550241 = 550312
101 + 550211 = 550312
131 + 550181 = 550312
149 + 550163 = 550312
173 + 550139 = 550312

Showing the first eight; more decompositions exist.
