Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640846, here are decompositions:

23 + 8640823 = 8640846
29 + 8640817 = 8640846
47 + 8640799 = 8640846
59 + 8640787 = 8640846
79 + 8640767 = 8640846
107 + 8640739 = 8640846
113 + 8640733 = 8640846
127 + 8640719 = 8640846

Showing the first eight; more decompositions exist.
