Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31770, here are decompositions:

19 + 31751 = 31770
29 + 31741 = 31770
41 + 31729 = 31770
43 + 31727 = 31770
47 + 31723 = 31770
71 + 31699 = 31770
83 + 31687 = 31770
103 + 31667 = 31770

Showing the first eight; more decompositions exist.
