Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31928, here are decompositions:

37 + 31891 = 31928
79 + 31849 = 31928
157 + 31771 = 31928
199 + 31729 = 31928
229 + 31699 = 31928
241 + 31687 = 31928
271 + 31657 = 31928
397 + 31531 = 31928

Showing the first eight; more decompositions exist.
