Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91564, here are decompositions:

23 + 91541 = 91564
71 + 91493 = 91564
101 + 91463 = 91564
107 + 91457 = 91564
131 + 91433 = 91564
167 + 91397 = 91564
191 + 91373 = 91564
197 + 91367 = 91564

Showing the first eight; more decompositions exist.
