Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8260, here are decompositions:

17 + 8243 = 8260
23 + 8237 = 8260
29 + 8231 = 8260
41 + 8219 = 8260
89 + 8171 = 8260
113 + 8147 = 8260
137 + 8123 = 8260
149 + 8111 = 8260

Showing the first eight; more decompositions exist.
