Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686564, here are decompositions:

101 + 8686463 = 8686564
167 + 8686397 = 8686564
191 + 8686373 = 8686564
251 + 8686313 = 8686564
401 + 8686163 = 8686564
443 + 8686121 = 8686564
461 + 8686103 = 8686564
563 + 8686001 = 8686564

Showing the first eight; more decompositions exist.
