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.
