Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658486, here are decompositions:

17 + 8658469 = 8658486
73 + 8658413 = 8658486
103 + 8658383 = 8658486
157 + 8658329 = 8658486
163 + 8658323 = 8658486
173 + 8658313 = 8658486
197 + 8658289 = 8658486
269 + 8658217 = 8658486

Showing the first eight; more decompositions exist.
