Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645964, here are decompositions:

23 + 8645941 = 8645964
37 + 8645927 = 8645964
101 + 8645863 = 8645964
191 + 8645773 = 8645964
277 + 8645687 = 8645964
307 + 8645657 = 8645964
311 + 8645653 = 8645964
317 + 8645647 = 8645964

Showing the first eight; more decompositions exist.
