Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018146, here are decompositions:

23 + 1018123 = 1018146
37 + 1018109 = 1018146
89 + 1018057 = 1018146
127 + 1018019 = 1018146
139 + 1018007 = 1018146
149 + 1017997 = 1018146
193 + 1017953 = 1018146
223 + 1017923 = 1018146

Showing the first eight; more decompositions exist.
