Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 782, here are decompositions:
- 13 + 769 = 782
- 31 + 751 = 782
- 43 + 739 = 782
- 73 + 709 = 782
- 109 + 673 = 782
- 139 + 643 = 782
- 151 + 631 = 782
- 163 + 619 = 782
Showing the first eight; more decompositions exist.
