Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 790, here are decompositions:
- 3 + 787 = 790
- 17 + 773 = 790
- 29 + 761 = 790
- 47 + 743 = 790
- 71 + 719 = 790
- 89 + 701 = 790
- 107 + 683 = 790
- 113 + 677 = 790
Showing the first eight; more decompositions exist.
