Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994778, here are decompositions:

61 + 994717 = 994778
67 + 994711 = 994778
79 + 994699 = 994778
157 + 994621 = 994778
199 + 994579 = 994778
229 + 994549 = 994778
277 + 994501 = 994778
307 + 994471 = 994778

Showing the first eight; more decompositions exist.
