Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717212, here are decompositions:

11 + 8717201 = 8717212
41 + 8717171 = 8717212
89 + 8717123 = 8717212
191 + 8717021 = 8717212
269 + 8716943 = 8717212
293 + 8716919 = 8717212
359 + 8716853 = 8717212
443 + 8716769 = 8717212

Showing the first eight; more decompositions exist.
