Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31682, here are decompositions:

19 + 31663 = 31682
109 + 31573 = 31682
139 + 31543 = 31682
151 + 31531 = 31682
193 + 31489 = 31682
349 + 31333 = 31682
433 + 31249 = 31682
463 + 31219 = 31682

Showing the first eight; more decompositions exist.
