Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994780, here are decompositions:

11 + 994769 = 994780
29 + 994751 = 994780
71 + 994709 = 994780
89 + 994691 = 994780
113 + 994667 = 994780
197 + 994583 = 994780
389 + 994391 = 994780
443 + 994337 = 994780

Showing the first eight; more decompositions exist.
