Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89784, here are decompositions:

5 + 89779 = 89784
17 + 89767 = 89784
31 + 89753 = 89784
103 + 89681 = 89784
113 + 89671 = 89784
127 + 89657 = 89784
131 + 89653 = 89784
151 + 89633 = 89784

Showing the first eight; more decompositions exist.
