Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647958, here are decompositions:

31 + 8647927 = 8647958
61 + 8647897 = 8647958
79 + 8647879 = 8647958
139 + 8647819 = 8647958
157 + 8647801 = 8647958
199 + 8647759 = 8647958
379 + 8647579 = 8647958
421 + 8647537 = 8647958

Showing the first eight; more decompositions exist.
