Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 788, here are decompositions:
- 19 + 769 = 788
- 31 + 757 = 788
- 37 + 751 = 788
- 61 + 727 = 788
- 79 + 709 = 788
- 97 + 691 = 788
- 127 + 661 = 788
- 157 + 631 = 788
Showing the first eight; more decompositions exist.
