Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91250, here are decompositions:
- 7 + 91243 = 91250
- 13 + 91237 = 91250
- 67 + 91183 = 91250
- 97 + 91153 = 91250
- 109 + 91141 = 91250
- 151 + 91099 = 91250
- 241 + 91009 = 91250
- 349 + 90901 = 91250
Showing the first eight; more decompositions exist.
