Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79690, here are decompositions:
- 3 + 79687 = 79690
- 59 + 79631 = 79690
- 89 + 79601 = 79690
- 101 + 79589 = 79690
- 131 + 79559 = 79690
- 197 + 79493 = 79690
- 239 + 79451 = 79690
- 257 + 79433 = 79690
Showing the first eight; more decompositions exist.
