Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91198, here are decompositions:
- 5 + 91193 = 91198
- 47 + 91151 = 91198
- 59 + 91139 = 91198
- 71 + 91127 = 91198
- 101 + 91097 = 91198
- 179 + 91019 = 91198
- 227 + 90971 = 91198
- 251 + 90947 = 91198
Showing the first eight; more decompositions exist.
