Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76770, here are decompositions:

13 + 76757 = 76770
17 + 76753 = 76770
37 + 76733 = 76770
53 + 76717 = 76770
73 + 76697 = 76770
97 + 76673 = 76770
103 + 76667 = 76770
139 + 76631 = 76770

Showing the first eight; more decompositions exist.
