Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550290, here are decompositions:

7 + 550283 = 550290
11 + 550279 = 550290
23 + 550267 = 550290
79 + 550211 = 550290
101 + 550189 = 550290
109 + 550181 = 550290
113 + 550177 = 550290
127 + 550163 = 550290

Showing the first eight; more decompositions exist.
