Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726664, here are decompositions:

17 + 8726647 = 8726664
31 + 8726633 = 8726664
53 + 8726611 = 8726664
131 + 8726533 = 8726664
137 + 8726527 = 8726664
157 + 8726507 = 8726664
197 + 8726467 = 8726664
263 + 8726401 = 8726664

Showing the first eight; more decompositions exist.
