Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712516, here are decompositions:

19 + 8712497 = 8712516
149 + 8712367 = 8712516
167 + 8712349 = 8712516
179 + 8712337 = 8712516
193 + 8712323 = 8712516
223 + 8712293 = 8712516
229 + 8712287 = 8712516
257 + 8712259 = 8712516

Showing the first eight; more decompositions exist.
