Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22664, here are decompositions:
- 13 + 22651 = 22664
- 43 + 22621 = 22664
- 97 + 22567 = 22664
- 163 + 22501 = 22664
- 181 + 22483 = 22664
- 211 + 22453 = 22664
- 223 + 22441 = 22664
- 283 + 22381 = 22664
Showing the first eight; more decompositions exist.
