Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658366, here are decompositions:

37 + 8658329 = 8658366
43 + 8658323 = 8658366
53 + 8658313 = 8658366
89 + 8658277 = 8658366
149 + 8658217 = 8658366
163 + 8658203 = 8658366
173 + 8658193 = 8658366
229 + 8658137 = 8658366

Showing the first eight; more decompositions exist.
