Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668942, here are decompositions:

41 + 8668901 = 8668942
53 + 8668889 = 8668942
179 + 8668763 = 8668942
389 + 8668553 = 8668942
419 + 8668523 = 8668942
521 + 8668421 = 8668942
563 + 8668379 = 8668942
593 + 8668349 = 8668942

Showing the first eight; more decompositions exist.
