Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994890, here are decompositions:

11 + 994879 = 994890
19 + 994871 = 994890
23 + 994867 = 994890
37 + 994853 = 994890
53 + 994837 = 994890
59 + 994831 = 994890
73 + 994817 = 994890
79 + 994811 = 994890

Showing the first eight; more decompositions exist.
