Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018422, here are decompositions:

11 + 1018411 = 1018422
109 + 1018313 = 1018422
113 + 1018309 = 1018422
131 + 1018291 = 1018422
151 + 1018271 = 1018422
199 + 1018223 = 1018422
313 + 1018109 = 1018422
331 + 1018091 = 1018422

Showing the first eight; more decompositions exist.
