Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91678, here are decompositions:

5 + 91673 = 91678
47 + 91631 = 91678
101 + 91577 = 91678
107 + 91571 = 91678
137 + 91541 = 91678
149 + 91529 = 91678
179 + 91499 = 91678
281 + 91397 = 91678

Showing the first eight; more decompositions exist.
