Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700790, here are decompositions:

17 + 8700773 = 8700790
23 + 8700767 = 8700790
191 + 8700599 = 8700790
227 + 8700563 = 8700790
251 + 8700539 = 8700790
269 + 8700521 = 8700790
317 + 8700473 = 8700790
359 + 8700431 = 8700790

Showing the first eight; more decompositions exist.
