Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91672, here are decompositions:
- 41 + 91631 = 91672
- 89 + 91583 = 91672
- 101 + 91571 = 91672
- 131 + 91541 = 91672
- 173 + 91499 = 91672
- 179 + 91493 = 91672
- 239 + 91433 = 91672
- 389 + 91283 = 91672
Showing the first eight; more decompositions exist.
