Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668738, here are decompositions:

17 + 8668721 = 8668738
41 + 8668697 = 8668738
101 + 8668637 = 8668738
167 + 8668571 = 8668738
191 + 8668547 = 8668738
317 + 8668421 = 8668738
359 + 8668379 = 8668738
389 + 8668349 = 8668738

Showing the first eight; more decompositions exist.
