Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91284, here are decompositions:

31 + 91253 = 91284
41 + 91243 = 91284
47 + 91237 = 91284
101 + 91183 = 91284
131 + 91153 = 91284
157 + 91127 = 91284
163 + 91121 = 91284
251 + 91033 = 91284

Showing the first eight; more decompositions exist.
