Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31964, here are decompositions:

7 + 31957 = 31964
73 + 31891 = 31964
193 + 31771 = 31964
223 + 31741 = 31964
241 + 31723 = 31964
277 + 31687 = 31964
307 + 31657 = 31964
337 + 31627 = 31964

Showing the first eight; more decompositions exist.
