Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518350, here are decompositions:

23 + 518327 = 518350
59 + 518291 = 518350
89 + 518261 = 518350
101 + 518249 = 518350
113 + 518237 = 518350
179 + 518171 = 518350
191 + 518159 = 518350
197 + 518153 = 518350

Showing the first eight; more decompositions exist.
