Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91390, here are decompositions:
- 3 + 91387 = 91390
- 17 + 91373 = 91390
- 23 + 91367 = 91390
- 59 + 91331 = 91390
- 107 + 91283 = 91390
- 137 + 91253 = 91390
- 191 + 91199 = 91390
- 197 + 91193 = 91390
Showing the first eight; more decompositions exist.
