Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91066, here are decompositions:

47 + 91019 = 91066
89 + 90977 = 91066
149 + 90917 = 91066
179 + 90887 = 91066
233 + 90833 = 91066
263 + 90803 = 91066
317 + 90749 = 91066
389 + 90677 = 91066

Showing the first eight; more decompositions exist.
