Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20744, here are decompositions:
- 13 + 20731 = 20744
- 37 + 20707 = 20744
- 103 + 20641 = 20744
- 151 + 20593 = 20744
- 181 + 20563 = 20744
- 193 + 20551 = 20744
- 211 + 20533 = 20744
- 223 + 20521 = 20744
Showing the first eight; more decompositions exist.
