Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31798, here are decompositions:

5 + 31793 = 31798
29 + 31769 = 31798
47 + 31751 = 31798
71 + 31727 = 31798
131 + 31667 = 31798
149 + 31649 = 31798
191 + 31607 = 31798
197 + 31601 = 31798

Showing the first eight; more decompositions exist.
