Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002770, here are decompositions:

3 + 1002767 = 1002770
19 + 1002751 = 1002770
31 + 1002739 = 1002770
61 + 1002709 = 1002770
151 + 1002619 = 1002770
193 + 1002577 = 1002770
277 + 1002493 = 1002770
283 + 1002487 = 1002770

Showing the first eight; more decompositions exist.
