Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79720, here are decompositions:
- 23 + 79697 = 79720
- 29 + 79691 = 79720
- 89 + 79631 = 79720
- 107 + 79613 = 79720
- 131 + 79589 = 79720
- 227 + 79493 = 79720
- 239 + 79481 = 79720
- 269 + 79451 = 79720
Showing the first eight; more decompositions exist.
