Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79638, here are decompositions:
- 5 + 79633 = 79638
- 7 + 79631 = 79638
- 11 + 79627 = 79638
- 17 + 79621 = 79638
- 29 + 79609 = 79638
- 37 + 79601 = 79638
- 59 + 79579 = 79638
- 79 + 79559 = 79638
Showing the first eight; more decompositions exist.
