Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20498, here are decompositions:
- 19 + 20479 = 20498
- 67 + 20431 = 20498
- 109 + 20389 = 20498
- 139 + 20359 = 20498
- 151 + 20347 = 20498
- 157 + 20341 = 20498
- 211 + 20287 = 20498
- 229 + 20269 = 20498
Showing the first eight; more decompositions exist.
