Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91258, here are decompositions:

5 + 91253 = 91258
29 + 91229 = 91258
59 + 91199 = 91258
107 + 91151 = 91258
131 + 91127 = 91258
137 + 91121 = 91258
179 + 91079 = 91258
239 + 91019 = 91258

Showing the first eight; more decompositions exist.
