Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20464, here are decompositions:
- 23 + 20441 = 20464
- 53 + 20411 = 20464
- 71 + 20393 = 20464
- 107 + 20357 = 20464
- 131 + 20333 = 20464
- 137 + 20327 = 20464
- 167 + 20297 = 20464
- 233 + 20231 = 20464
Showing the first eight; more decompositions exist.
