Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76778, here are decompositions:

7 + 76771 = 76778
61 + 76717 = 76778
127 + 76651 = 76778
181 + 76597 = 76778
199 + 76579 = 76778
241 + 76537 = 76778
271 + 76507 = 76778
307 + 76471 = 76778

Showing the first eight; more decompositions exist.
