Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994978, here are decompositions:

29 + 994949 = 994978
71 + 994907 = 994978
107 + 994871 = 994978
167 + 994811 = 994978
227 + 994751 = 994978
269 + 994709 = 994978
311 + 994667 = 994978
419 + 994559 = 994978

Showing the first eight; more decompositions exist.
