Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22238, here are decompositions:
- 67 + 22171 = 22238
- 79 + 22159 = 22238
- 109 + 22129 = 22238
- 127 + 22111 = 22238
- 199 + 22039 = 22238
- 211 + 22027 = 22238
- 241 + 21997 = 22238
- 277 + 21961 = 22238
Showing the first eight; more decompositions exist.
