Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77894, here are decompositions:

31 + 77863 = 77894
97 + 77797 = 77894
151 + 77743 = 77894
163 + 77731 = 77894
181 + 77713 = 77894
277 + 77617 = 77894
283 + 77611 = 77894
307 + 77587 = 77894

Showing the first eight; more decompositions exist.
