Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702668, here are decompositions:

5 + 8702663 = 8702668
71 + 8702597 = 8702668
179 + 8702489 = 8702668
257 + 8702411 = 8702668
281 + 8702387 = 8702668
389 + 8702279 = 8702668
461 + 8702207 = 8702668
479 + 8702189 = 8702668

Showing the first eight; more decompositions exist.
