Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22972, here are decompositions:
- 11 + 22961 = 22972
- 29 + 22943 = 22972
- 71 + 22901 = 22972
- 101 + 22871 = 22972
- 113 + 22859 = 22972
- 233 + 22739 = 22972
- 251 + 22721 = 22972
- 263 + 22709 = 22972
Showing the first eight; more decompositions exist.
