Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931928, here are decompositions:

7 + 931921 = 931928
79 + 931849 = 931928
139 + 931789 = 931928
181 + 931747 = 931928
199 + 931729 = 931928
271 + 931657 = 931928
307 + 931621 = 931928
331 + 931597 = 931928

Showing the first eight; more decompositions exist.
