Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22400, here are decompositions:
- 3 + 22397 = 22400
- 19 + 22381 = 22400
- 31 + 22369 = 22400
- 97 + 22303 = 22400
- 109 + 22291 = 22400
- 127 + 22273 = 22400
- 211 + 22189 = 22400
- 229 + 22171 = 22400
Showing the first eight; more decompositions exist.
