Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939984, here are decompositions:

11 + 939973 = 939984
13 + 939971 = 939984
53 + 939931 = 939984
61 + 939923 = 939984
83 + 939901 = 939984
103 + 939881 = 939984
113 + 939871 = 939984
131 + 939853 = 939984

Showing the first eight; more decompositions exist.
