Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668586, here are decompositions:

37 + 8668549 = 8668586
67 + 8668519 = 8668586
97 + 8668489 = 8668586
103 + 8668483 = 8668586
127 + 8668459 = 8668586
163 + 8668423 = 8668586
229 + 8668357 = 8668586
307 + 8668279 = 8668586

Showing the first eight; more decompositions exist.
