Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550386, here are decompositions:

7 + 550379 = 550386
17 + 550369 = 550386
97 + 550289 = 550386
103 + 550283 = 550386
107 + 550279 = 550386
173 + 550213 = 550386
197 + 550189 = 550386
223 + 550163 = 550386

Showing the first eight; more decompositions exist.
