Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018506, here are decompositions:

17 + 1018489 = 1018506
29 + 1018477 = 1018506
59 + 1018447 = 1018506
67 + 1018439 = 1018506
149 + 1018357 = 1018506
193 + 1018313 = 1018506
197 + 1018309 = 1018506
283 + 1018223 = 1018506

Showing the first eight; more decompositions exist.
