Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939980, here are decompositions:

7 + 939973 = 939980
79 + 939901 = 939980
109 + 939871 = 939980
127 + 939853 = 939980
157 + 939823 = 939980
211 + 939769 = 939980
241 + 939739 = 939980
331 + 939649 = 939980

Showing the first eight; more decompositions exist.
