Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77670, here are decompositions:

11 + 77659 = 77670
23 + 77647 = 77670
29 + 77641 = 77670
53 + 77617 = 77670
59 + 77611 = 77670
79 + 77591 = 77670
83 + 77587 = 77670
97 + 77573 = 77670

Showing the first eight; more decompositions exist.
