Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647946, here are decompositions:

19 + 8647927 = 8647946
67 + 8647879 = 8647946
127 + 8647819 = 8647946
163 + 8647783 = 8647946
193 + 8647753 = 8647946
367 + 8647579 = 8647946
379 + 8647567 = 8647946
409 + 8647537 = 8647946

Showing the first eight; more decompositions exist.
