Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686624, here are decompositions:

137 + 8686487 = 8686624
227 + 8686397 = 8686624
251 + 8686373 = 8686624
263 + 8686361 = 8686624
311 + 8686313 = 8686624
347 + 8686277 = 8686624
383 + 8686241 = 8686624
431 + 8686193 = 8686624

Showing the first eight; more decompositions exist.
