Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994988, here are decompositions:

61 + 994927 = 994988
109 + 994879 = 994988
151 + 994837 = 994988
157 + 994831 = 994988
271 + 994717 = 994988
277 + 994711 = 994988
331 + 994657 = 994988
367 + 994621 = 994988

Showing the first eight; more decompositions exist.
