Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668494, here are decompositions:

5 + 8668489 = 8668494
11 + 8668483 = 8668494
71 + 8668423 = 8668494
73 + 8668421 = 8668494
113 + 8668381 = 8668494
127 + 8668367 = 8668494
137 + 8668357 = 8668494
193 + 8668301 = 8668494

Showing the first eight; more decompositions exist.
