Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018090, here are decompositions:

71 + 1018019 = 1018090
83 + 1018007 = 1018090
131 + 1017959 = 1018090
137 + 1017953 = 1018090
167 + 1017923 = 1018090
233 + 1017857 = 1018090
239 + 1017851 = 1018090
263 + 1017827 = 1018090

Showing the first eight; more decompositions exist.
