Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938980, here are decompositions:

11 + 938969 = 938980
17 + 938963 = 938980
41 + 938939 = 938980
59 + 938921 = 938980
101 + 938879 = 938980
137 + 938843 = 938980
149 + 938831 = 938980
173 + 938807 = 938980

Showing the first eight; more decompositions exist.
