Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67778, here are decompositions:

19 + 67759 = 67778
37 + 67741 = 67778
79 + 67699 = 67778
127 + 67651 = 67778
199 + 67579 = 67778
211 + 67567 = 67778
241 + 67537 = 67778
331 + 67447 = 67778

Showing the first eight; more decompositions exist.
