Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31748, here are decompositions:

7 + 31741 = 31748
19 + 31729 = 31748
61 + 31687 = 31748
181 + 31567 = 31748
271 + 31477 = 31748
421 + 31327 = 31748
499 + 31249 = 31748
571 + 31177 = 31748

Showing the first eight; more decompositions exist.
