Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704778, here are decompositions:

67 + 8704711 = 8704778
79 + 8704699 = 8704778
127 + 8704651 = 8704778
157 + 8704621 = 8704778
211 + 8704567 = 8704778
409 + 8704369 = 8704778
499 + 8704279 = 8704778
619 + 8704159 = 8704778

Showing the first eight; more decompositions exist.
