Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668894, here are decompositions:

5 + 8668889 = 8668894
131 + 8668763 = 8668894
173 + 8668721 = 8668894
197 + 8668697 = 8668894
251 + 8668643 = 8668894
257 + 8668637 = 8668894
281 + 8668613 = 8668894
317 + 8668577 = 8668894

Showing the first eight; more decompositions exist.
