Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018170, here are decompositions:

47 + 1018123 = 1018170
61 + 1018109 = 1018170
73 + 1018097 = 1018170
79 + 1018091 = 1018170
113 + 1018057 = 1018170
149 + 1018021 = 1018170
151 + 1018019 = 1018170
163 + 1018007 = 1018170

Showing the first eight; more decompositions exist.
