Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8290, here are decompositions:

3 + 8287 = 8290
17 + 8273 = 8290
47 + 8243 = 8290
53 + 8237 = 8290
59 + 8231 = 8290
71 + 8219 = 8290
167 + 8123 = 8290
173 + 8117 = 8290

Showing the first eight; more decompositions exist.
