Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642682, here are decompositions:

31 + 8642651 = 8642682
101 + 8642581 = 8642682
149 + 8642533 = 8642682
163 + 8642519 = 8642682
173 + 8642509 = 8642682
193 + 8642489 = 8642682
229 + 8642453 = 8642682
233 + 8642449 = 8642682

Showing the first eight; more decompositions exist.
