Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994880, here are decompositions:

13 + 994867 = 994880
43 + 994837 = 994880
67 + 994813 = 994880
157 + 994723 = 994880
163 + 994717 = 994880
181 + 994699 = 994880
223 + 994657 = 994880
277 + 994603 = 994880

Showing the first eight; more decompositions exist.
