Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939028, here are decompositions:

17 + 939011 = 939028
47 + 938981 = 939028
59 + 938969 = 939028
89 + 938939 = 939028
107 + 938921 = 939028
149 + 938879 = 939028
197 + 938831 = 939028
281 + 938747 = 939028

Showing the first eight; more decompositions exist.
