Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670288, here are decompositions:

7 + 8670281 = 8670288
31 + 8670257 = 8670288
97 + 8670191 = 8670288
131 + 8670157 = 8670288
181 + 8670107 = 8670288
199 + 8670089 = 8670288
251 + 8670037 = 8670288
257 + 8670031 = 8670288

Showing the first eight; more decompositions exist.
