Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31914, here are decompositions:

7 + 31907 = 31914
23 + 31891 = 31914
31 + 31883 = 31914
41 + 31873 = 31914
67 + 31847 = 31914
97 + 31817 = 31914
163 + 31751 = 31914
173 + 31741 = 31914

Showing the first eight; more decompositions exist.
