Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018600, here are decompositions:

17 + 1018583 = 1018600
41 + 1018559 = 1018600
179 + 1018421 = 1018600
263 + 1018337 = 1018600
347 + 1018253 = 1018600
353 + 1018247 = 1018600
383 + 1018217 = 1018600
491 + 1018109 = 1018600

Showing the first eight; more decompositions exist.
