Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28822, here are decompositions:
- 5 + 28817 = 28822
- 29 + 28793 = 28822
- 71 + 28751 = 28822
- 173 + 28649 = 28822
- 179 + 28643 = 28822
- 191 + 28631 = 28822
- 251 + 28571 = 28822
- 263 + 28559 = 28822
Showing the first eight; more decompositions exist.
