Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657678, here are decompositions:

67 + 8657611 = 8657678
109 + 8657569 = 8657678
229 + 8657449 = 8657678
439 + 8657239 = 8657678
457 + 8657221 = 8657678
661 + 8657017 = 8657678
739 + 8656939 = 8657678
787 + 8656891 = 8657678

Showing the first eight; more decompositions exist.
