Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645994, here are decompositions:

13 + 8645981 = 8645994
23 + 8645971 = 8645994
53 + 8645941 = 8645994
67 + 8645927 = 8645994
107 + 8645887 = 8645994
131 + 8645863 = 8645994
191 + 8645803 = 8645994
233 + 8645761 = 8645994

Showing the first eight; more decompositions exist.
