Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618616, here are decompositions:

23 + 8618593 = 8618616
59 + 8618557 = 8618616
137 + 8618479 = 8618616
173 + 8618443 = 8618616
229 + 8618387 = 8618616
239 + 8618377 = 8618616
277 + 8618339 = 8618616
359 + 8618257 = 8618616

Showing the first eight; more decompositions exist.
