Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931998, here are decompositions:

17 + 931981 = 931998
31 + 931967 = 931998
97 + 931901 = 931998
139 + 931859 = 931998
149 + 931849 = 931998
241 + 931757 = 931998
251 + 931747 = 931998
269 + 931729 = 931998

Showing the first eight; more decompositions exist.
