Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20276, here are decompositions:
- 7 + 20269 = 20276
- 43 + 20233 = 20276
- 103 + 20173 = 20276
- 127 + 20149 = 20276
- 163 + 20113 = 20276
- 229 + 20047 = 20276
- 283 + 19993 = 20276
- 313 + 19963 = 20276
Showing the first eight; more decompositions exist.
