Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31750, here are decompositions:

23 + 31727 = 31750
29 + 31721 = 31750
83 + 31667 = 31750
101 + 31649 = 31750
107 + 31643 = 31750
149 + 31601 = 31750
167 + 31583 = 31750
233 + 31517 = 31750

Showing the first eight; more decompositions exist.
