Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91372, here are decompositions:
- 3 + 91369 = 91372
- 5 + 91367 = 91372
- 41 + 91331 = 91372
- 89 + 91283 = 91372
- 173 + 91199 = 91372
- 179 + 91193 = 91372
- 233 + 91139 = 91372
- 251 + 91121 = 91372
Showing the first eight; more decompositions exist.
