Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717286, here are decompositions:

13 + 8717273 = 8717286
23 + 8717263 = 8717286
47 + 8717239 = 8717286
73 + 8717213 = 8717286
163 + 8717123 = 8717286
167 + 8717119 = 8717286
173 + 8717113 = 8717286
367 + 8716919 = 8717286

Showing the first eight; more decompositions exist.
