Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641794, here are decompositions:

11 + 8641783 = 8641794
13 + 8641781 = 8641794
47 + 8641747 = 8641794
53 + 8641741 = 8641794
61 + 8641733 = 8641794
97 + 8641697 = 8641794
151 + 8641643 = 8641794
163 + 8641631 = 8641794

Showing the first eight; more decompositions exist.
