Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22422, here are decompositions:
- 13 + 22409 = 22422
- 31 + 22391 = 22422
- 41 + 22381 = 22422
- 53 + 22369 = 22422
- 73 + 22349 = 22422
- 79 + 22343 = 22422
- 131 + 22291 = 22422
- 139 + 22283 = 22422
Showing the first eight; more decompositions exist.
