Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22784, here are decompositions:
- 7 + 22777 = 22784
- 43 + 22741 = 22784
- 67 + 22717 = 22784
- 163 + 22621 = 22784
- 211 + 22573 = 22784
- 241 + 22543 = 22784
- 283 + 22501 = 22784
- 331 + 22453 = 22784
Showing the first eight; more decompositions exist.
