Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702818, here are decompositions:

41 + 8702777 = 8702818
71 + 8702747 = 8702818
227 + 8702591 = 8702818
359 + 8702459 = 8702818
431 + 8702387 = 8702818
491 + 8702327 = 8702818
587 + 8702231 = 8702818
659 + 8702159 = 8702818

Showing the first eight; more decompositions exist.
