Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668616, here are decompositions:

3 + 8668613 = 8668616
7 + 8668609 = 8668616
67 + 8668549 = 8668616
97 + 8668519 = 8668616
127 + 8668489 = 8668616
157 + 8668459 = 8668616
193 + 8668423 = 8668616
337 + 8668279 = 8668616

Showing the first eight; more decompositions exist.
