Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31684, here are decompositions:

17 + 31667 = 31684
41 + 31643 = 31684
83 + 31601 = 31684
101 + 31583 = 31684
137 + 31547 = 31684
167 + 31517 = 31684
173 + 31511 = 31684
293 + 31391 = 31684

Showing the first eight; more decompositions exist.
