Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645682, here are decompositions:

13 + 8645669 = 8645682
29 + 8645653 = 8645682
103 + 8645579 = 8645682
139 + 8645543 = 8645682
191 + 8645491 = 8645682
233 + 8645449 = 8645682
239 + 8645443 = 8645682
251 + 8645431 = 8645682

Showing the first eight; more decompositions exist.
