Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648, here are decompositions:

7 + 8641 = 8648
19 + 8629 = 8648
67 + 8581 = 8648
109 + 8539 = 8648
127 + 8521 = 8648
181 + 8467 = 8648
229 + 8419 = 8648
271 + 8377 = 8648

Showing the first eight; more decompositions exist.
