Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645726, here are decompositions:

7 + 8645719 = 8645726
73 + 8645653 = 8645726
79 + 8645647 = 8645726
109 + 8645617 = 8645726
139 + 8645587 = 8645726
277 + 8645449 = 8645726
283 + 8645443 = 8645726
367 + 8645359 = 8645726

Showing the first eight; more decompositions exist.
