Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702788, here are decompositions:

11 + 8702777 = 8702788
41 + 8702747 = 8702788
89 + 8702699 = 8702788
191 + 8702597 = 8702788
197 + 8702591 = 8702788
401 + 8702387 = 8702788
461 + 8702327 = 8702788
509 + 8702279 = 8702788

Showing the first eight; more decompositions exist.
