Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91642, here are decompositions:
- 3 + 91639 = 91642
- 11 + 91631 = 91642
- 59 + 91583 = 91642
- 71 + 91571 = 91642
- 101 + 91541 = 91642
- 113 + 91529 = 91642
- 149 + 91493 = 91642
- 179 + 91463 = 91642
Showing the first eight; more decompositions exist.
