Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89778, here are decompositions:

11 + 89767 = 89778
19 + 89759 = 89778
89 + 89689 = 89778
97 + 89681 = 89778
107 + 89671 = 89778
109 + 89669 = 89778
151 + 89627 = 89778
167 + 89611 = 89778

Showing the first eight; more decompositions exist.
