Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31934, here are decompositions:

43 + 31891 = 31934
61 + 31873 = 31934
163 + 31771 = 31934
193 + 31741 = 31934
211 + 31723 = 31934
271 + 31663 = 31934
277 + 31657 = 31934
307 + 31627 = 31934

Showing the first eight; more decompositions exist.
