Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91156, here are decompositions:
- 3 + 91153 = 91156
- 5 + 91151 = 91156
- 17 + 91139 = 91156
- 29 + 91127 = 91156
- 59 + 91097 = 91156
- 137 + 91019 = 91156
- 167 + 90989 = 91156
- 179 + 90977 = 91156
Showing the first eight; more decompositions exist.
