Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643946, here are decompositions:

5 + 8643941 = 8643946
23 + 8643923 = 8643946
53 + 8643893 = 8643946
107 + 8643839 = 8643946
149 + 8643797 = 8643946
167 + 8643779 = 8643946
197 + 8643749 = 8643946
239 + 8643707 = 8643946

Showing the first eight; more decompositions exist.
