Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743966, here are decompositions:

3 + 8743963 = 8743966
29 + 8743937 = 8743966
47 + 8743919 = 8743966
53 + 8743913 = 8743966
83 + 8743883 = 8743966
113 + 8743853 = 8743966
149 + 8743817 = 8743966
197 + 8743769 = 8743966

Showing the first eight; more decompositions exist.
