Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646736, here are decompositions:

17 + 8646719 = 8646736
29 + 8646707 = 8646736
53 + 8646683 = 8646736
233 + 8646503 = 8646736
239 + 8646497 = 8646736
257 + 8646479 = 8646736
347 + 8646389 = 8646736
359 + 8646377 = 8646736

Showing the first eight; more decompositions exist.
