Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018582, here are decompositions:

23 + 1018559 = 1018582
269 + 1018313 = 1018582
281 + 1018301 = 1018582
311 + 1018271 = 1018582
359 + 1018223 = 1018582
491 + 1018091 = 1018582
563 + 1018019 = 1018582
659 + 1017923 = 1018582

Showing the first eight; more decompositions exist.
