Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8464, here are decompositions:

3 + 8461 = 8464
17 + 8447 = 8464
41 + 8423 = 8464
101 + 8363 = 8464
167 + 8297 = 8464
173 + 8291 = 8464
191 + 8273 = 8464
227 + 8237 = 8464

Showing the first eight; more decompositions exist.
