Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102768, here are decompositions:

5 + 102763 = 102768
7 + 102761 = 102768
67 + 102701 = 102768
89 + 102679 = 102768
101 + 102667 = 102768
157 + 102611 = 102768
181 + 102587 = 102768
229 + 102539 = 102768

Showing the first eight; more decompositions exist.
