Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931984, here are decompositions:

3 + 931981 = 931984
17 + 931967 = 931984
41 + 931943 = 931984
71 + 931913 = 931984
83 + 931901 = 931984
101 + 931883 = 931984
107 + 931877 = 931984
173 + 931811 = 931984

Showing the first eight; more decompositions exist.
