Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28744, here are decompositions:
- 41 + 28703 = 28744
- 47 + 28697 = 28744
- 83 + 28661 = 28744
- 101 + 28643 = 28744
- 113 + 28631 = 28744
- 137 + 28607 = 28744
- 173 + 28571 = 28744
- 197 + 28547 = 28744
Showing the first eight; more decompositions exist.
