Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79660, here are decompositions:
- 3 + 79657 = 79660
- 29 + 79631 = 79660
- 47 + 79613 = 79660
- 59 + 79601 = 79660
- 71 + 79589 = 79660
- 101 + 79559 = 79660
- 167 + 79493 = 79660
- 179 + 79481 = 79660
Showing the first eight; more decompositions exist.
