Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31904, here are decompositions:

13 + 31891 = 31904
31 + 31873 = 31904
163 + 31741 = 31904
181 + 31723 = 31904
241 + 31663 = 31904
277 + 31627 = 31904
331 + 31573 = 31904
337 + 31567 = 31904

Showing the first eight; more decompositions exist.
