Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645982, here are decompositions:

11 + 8645971 = 8645982
41 + 8645941 = 8645982
83 + 8645899 = 8645982
179 + 8645803 = 8645982
193 + 8645789 = 8645982
223 + 8645759 = 8645982
263 + 8645719 = 8645982
313 + 8645669 = 8645982

Showing the first eight; more decompositions exist.
