Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018222, here are decompositions:

5 + 1018217 = 1018222
113 + 1018109 = 1018222
131 + 1018091 = 1018222
263 + 1017959 = 1018222
269 + 1017953 = 1018222
503 + 1017719 = 1018222
509 + 1017713 = 1018222
599 + 1017623 = 1018222

Showing the first eight; more decompositions exist.
