Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76642, here are decompositions:
- 11 + 76631 = 76642
- 101 + 76541 = 76642
- 131 + 76511 = 76642
- 149 + 76493 = 76642
- 179 + 76463 = 76642
- 239 + 76403 = 76642
- 263 + 76379 = 76642
- 353 + 76289 = 76642
Showing the first eight; more decompositions exist.
