Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663946, here are decompositions:

23 + 8663923 = 8663946
47 + 8663899 = 8663946
127 + 8663819 = 8663946
139 + 8663807 = 8663946
149 + 8663797 = 8663946
227 + 8663719 = 8663946
293 + 8663653 = 8663946
337 + 8663609 = 8663946

Showing the first eight; more decompositions exist.
