Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727678, here are decompositions:

5 + 8727673 = 8727678
19 + 8727659 = 8727678
59 + 8727619 = 8727678
67 + 8727611 = 8727678
79 + 8727599 = 8727678
101 + 8727577 = 8727678
109 + 8727569 = 8727678
139 + 8727539 = 8727678

Showing the first eight; more decompositions exist.
