Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8778, here are decompositions:

17 + 8761 = 8778
31 + 8747 = 8778
37 + 8741 = 8778
41 + 8737 = 8778
47 + 8731 = 8778
59 + 8719 = 8778
71 + 8707 = 8778
79 + 8699 = 8778

Showing the first eight; more decompositions exist.
