Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018522, here are decompositions:

83 + 1018439 = 1018522
101 + 1018421 = 1018522
251 + 1018271 = 1018522
269 + 1018253 = 1018522
431 + 1018091 = 1018522
503 + 1018019 = 1018522
563 + 1017959 = 1018522
569 + 1017953 = 1018522

Showing the first eight; more decompositions exist.
