Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018166, here are decompositions:

43 + 1018123 = 1018166
109 + 1018057 = 1018166
277 + 1017889 = 1018166
307 + 1017859 = 1018166
349 + 1017817 = 1018166
367 + 1017799 = 1018166
379 + 1017787 = 1018166
463 + 1017703 = 1018166

Showing the first eight; more decompositions exist.
