Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20450, here are decompositions:
- 7 + 20443 = 20450
- 19 + 20431 = 20450
- 43 + 20407 = 20450
- 61 + 20389 = 20450
- 97 + 20353 = 20450
- 103 + 20347 = 20450
- 109 + 20341 = 20450
- 127 + 20323 = 20450
Showing the first eight; more decompositions exist.
