Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27722, here are decompositions:
- 31 + 27691 = 27722
- 139 + 27583 = 27722
- 181 + 27541 = 27722
- 193 + 27529 = 27722
- 241 + 27481 = 27722
- 313 + 27409 = 27722
- 439 + 27283 = 27722
- 463 + 27259 = 27722
Showing the first eight; more decompositions exist.
