Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22320, here are decompositions:
- 13 + 22307 = 22320
- 17 + 22303 = 22320
- 29 + 22291 = 22320
- 37 + 22283 = 22320
- 41 + 22279 = 22320
- 43 + 22277 = 22320
- 47 + 22273 = 22320
- 61 + 22259 = 22320
Showing the first eight; more decompositions exist.
