Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994720, here are decompositions:

3 + 994717 = 994720
11 + 994709 = 994720
29 + 994691 = 994720
53 + 994667 = 994720
137 + 994583 = 994720
149 + 994571 = 994720
263 + 994457 = 994720
383 + 994337 = 994720

Showing the first eight; more decompositions exist.
