Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668516, here are decompositions:

113 + 8668403 = 8668516
137 + 8668379 = 8668516
149 + 8668367 = 8668516
167 + 8668349 = 8668516
359 + 8668157 = 8668516
383 + 8668133 = 8668516
443 + 8668073 = 8668516
449 + 8668067 = 8668516

Showing the first eight; more decompositions exist.
