Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645684, here are decompositions:

31 + 8645653 = 8645684
37 + 8645647 = 8645684
67 + 8645617 = 8645684
97 + 8645587 = 8645684
193 + 8645491 = 8645684
241 + 8645443 = 8645684
277 + 8645407 = 8645684
331 + 8645353 = 8645684

Showing the first eight; more decompositions exist.
