Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981994, here are decompositions:

11 + 981983 = 981994
47 + 981947 = 981994
53 + 981941 = 981994
107 + 981887 = 981994
197 + 981797 = 981994
263 + 981731 = 981994
281 + 981713 = 981994
311 + 981683 = 981994

Showing the first eight; more decompositions exist.
