Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20468, here are decompositions:
- 37 + 20431 = 20468
- 61 + 20407 = 20468
- 79 + 20389 = 20468
- 109 + 20359 = 20468
- 127 + 20341 = 20468
- 181 + 20287 = 20468
- 199 + 20269 = 20468
- 307 + 20161 = 20468
Showing the first eight; more decompositions exist.
