Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31912, here are decompositions:

5 + 31907 = 31912
29 + 31883 = 31912
53 + 31859 = 31912
113 + 31799 = 31912
191 + 31721 = 31912
263 + 31649 = 31912
269 + 31643 = 31912
311 + 31601 = 31912

Showing the first eight; more decompositions exist.
