Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20654, here are decompositions:
- 13 + 20641 = 20654
- 43 + 20611 = 20654
- 61 + 20593 = 20654
- 103 + 20551 = 20654
- 211 + 20443 = 20654
- 223 + 20431 = 20654
- 307 + 20347 = 20654
- 313 + 20341 = 20654
Showing the first eight; more decompositions exist.
