Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639950, here are decompositions:

29 + 8639921 = 8639950
41 + 8639909 = 8639950
47 + 8639903 = 8639950
101 + 8639849 = 8639950
113 + 8639837 = 8639950
131 + 8639819 = 8639950
197 + 8639753 = 8639950
239 + 8639711 = 8639950

Showing the first eight; more decompositions exist.
