Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99778, here are decompositions:

11 + 99767 = 99778
17 + 99761 = 99778
59 + 99719 = 99778
71 + 99707 = 99778
89 + 99689 = 99778
167 + 99611 = 99778
197 + 99581 = 99778
227 + 99551 = 99778

Showing the first eight; more decompositions exist.
