Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018140, here are decompositions:

17 + 1018123 = 1018140
31 + 1018109 = 1018140
43 + 1018097 = 1018140
83 + 1018057 = 1018140
181 + 1017959 = 1018140
251 + 1017889 = 1018140
281 + 1017859 = 1018140
283 + 1017857 = 1018140

Showing the first eight; more decompositions exist.
