Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645946, here are decompositions:

5 + 8645941 = 8645946
19 + 8645927 = 8645946
47 + 8645899 = 8645946
59 + 8645887 = 8645946
83 + 8645863 = 8645946
97 + 8645849 = 8645946
157 + 8645789 = 8645946
173 + 8645773 = 8645946

Showing the first eight; more decompositions exist.
