Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102770, here are decompositions:

7 + 102763 = 102770
97 + 102673 = 102770
103 + 102667 = 102770
127 + 102643 = 102770
163 + 102607 = 102770
211 + 102559 = 102770
223 + 102547 = 102770
271 + 102499 = 102770

Showing the first eight; more decompositions exist.
