Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8410, here are decompositions:

23 + 8387 = 8410
41 + 8369 = 8410
47 + 8363 = 8410
113 + 8297 = 8410
137 + 8273 = 8410
167 + 8243 = 8410
173 + 8237 = 8410
179 + 8231 = 8410

Showing the first eight; more decompositions exist.
