Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646616, here are decompositions:

113 + 8646503 = 8646616
137 + 8646479 = 8646616
227 + 8646389 = 8646616
239 + 8646377 = 8646616
317 + 8646299 = 8646616
347 + 8646269 = 8646616
359 + 8646257 = 8646616
383 + 8646233 = 8646616

Showing the first eight; more decompositions exist.
