Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91278, here are decompositions:

29 + 91249 = 91278
41 + 91237 = 91278
79 + 91199 = 91278
127 + 91151 = 91278
137 + 91141 = 91278
139 + 91139 = 91278
149 + 91129 = 91278
151 + 91127 = 91278

Showing the first eight; more decompositions exist.
