Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686446, here are decompositions:

37 + 8686409 = 8686446
73 + 8686373 = 8686446
137 + 8686309 = 8686446
149 + 8686297 = 8686446
173 + 8686273 = 8686446
233 + 8686213 = 8686446
239 + 8686207 = 8686446
257 + 8686189 = 8686446

Showing the first eight; more decompositions exist.
