Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101770, here are decompositions:

23 + 101747 = 101770
29 + 101741 = 101770
47 + 101723 = 101770
89 + 101681 = 101770
107 + 101663 = 101770
167 + 101603 = 101770
197 + 101573 = 101770
233 + 101537 = 101770

Showing the first eight; more decompositions exist.
