Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 662, here are decompositions:
- 3 + 659 = 662
- 19 + 643 = 662
- 31 + 631 = 662
- 43 + 619 = 662
- 61 + 601 = 662
- 139 + 523 = 662
- 163 + 499 = 662
- 199 + 463 = 662
Showing the first eight; more decompositions exist.
