Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657726, here are decompositions:

3 + 8657723 = 8657726
97 + 8657629 = 8657726
157 + 8657569 = 8657726
163 + 8657563 = 8657726
193 + 8657533 = 8657726
223 + 8657503 = 8657726
277 + 8657449 = 8657726
349 + 8657377 = 8657726

Showing the first eight; more decompositions exist.
