Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618074, here are decompositions:

11 + 8618063 = 8618074
41 + 8618033 = 8618074
53 + 8618021 = 8618074
83 + 8617991 = 8618074
131 + 8617943 = 8618074
197 + 8617877 = 8618074
251 + 8617823 = 8618074
677 + 8617397 = 8618074

Showing the first eight; more decompositions exist.
