Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20382, here are decompositions:
- 13 + 20369 = 20382
- 23 + 20359 = 20382
- 29 + 20353 = 20382
- 41 + 20341 = 20382
- 59 + 20323 = 20382
- 113 + 20269 = 20382
- 149 + 20233 = 20382
- 151 + 20231 = 20382
Showing the first eight; more decompositions exist.
