Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645708, here are decompositions:

61 + 8645647 = 8645708
277 + 8645431 = 8645708
349 + 8645359 = 8645708
367 + 8645341 = 8645708
439 + 8645269 = 8645708
661 + 8645047 = 8645708
751 + 8644957 = 8645708
937 + 8644771 = 8645708

Showing the first eight; more decompositions exist.
