Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8278, here are decompositions:

5 + 8273 = 8278
41 + 8237 = 8278
47 + 8231 = 8278
59 + 8219 = 8278
107 + 8171 = 8278
131 + 8147 = 8278
167 + 8111 = 8278
191 + 8087 = 8278

Showing the first eight; more decompositions exist.
