Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91240, here are decompositions:
- 3 + 91237 = 91240
- 11 + 91229 = 91240
- 41 + 91199 = 91240
- 47 + 91193 = 91240
- 89 + 91151 = 91240
- 101 + 91139 = 91240
- 113 + 91127 = 91240
- 251 + 90989 = 91240
Showing the first eight; more decompositions exist.
