Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658718, here are decompositions:

41 + 8658677 = 8658718
59 + 8658659 = 8658718
137 + 8658581 = 8658718
149 + 8658569 = 8658718
191 + 8658527 = 8658718
347 + 8658371 = 8658718
389 + 8658329 = 8658718
557 + 8658161 = 8658718

Showing the first eight; more decompositions exist.
