Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639956, here are decompositions:

5 + 8639951 = 8639956
47 + 8639909 = 8639956
53 + 8639903 = 8639956
107 + 8639849 = 8639956
137 + 8639819 = 8639956
293 + 8639663 = 8639956
317 + 8639639 = 8639956
359 + 8639597 = 8639956

Showing the first eight; more decompositions exist.
