Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77684, here are decompositions:

3 + 77681 = 77684
37 + 77647 = 77684
43 + 77641 = 77684
67 + 77617 = 77684
73 + 77611 = 77684
97 + 77587 = 77684
127 + 77557 = 77684
157 + 77527 = 77684

Showing the first eight; more decompositions exist.
