Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79680, here are decompositions:
- 11 + 79669 = 79680
- 23 + 79657 = 79680
- 47 + 79633 = 79680
- 53 + 79627 = 79680
- 59 + 79621 = 79680
- 67 + 79613 = 79680
- 71 + 79609 = 79680
- 79 + 79601 = 79680
Showing the first eight; more decompositions exist.
