Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20554, here are decompositions:
- 3 + 20551 = 20554
- 5 + 20549 = 20554
- 11 + 20543 = 20554
- 47 + 20507 = 20554
- 71 + 20483 = 20554
- 113 + 20441 = 20554
- 197 + 20357 = 20554
- 227 + 20327 = 20554
Showing the first eight; more decompositions exist.
