Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22388, here are decompositions:
- 7 + 22381 = 22388
- 19 + 22369 = 22388
- 97 + 22291 = 22388
- 109 + 22279 = 22388
- 199 + 22189 = 22388
- 229 + 22159 = 22388
- 241 + 22147 = 22388
- 277 + 22111 = 22388
Showing the first eight; more decompositions exist.
