Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67788, here are decompositions:

5 + 67783 = 67788
11 + 67777 = 67788
29 + 67759 = 67788
31 + 67757 = 67788
37 + 67751 = 67788
47 + 67741 = 67788
79 + 67709 = 67788
89 + 67699 = 67788

Showing the first eight; more decompositions exist.
