Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43890, here are decompositions:
- 23 + 43867 = 43890
- 37 + 43853 = 43890
- 89 + 43801 = 43890
- 97 + 43793 = 43890
- 101 + 43789 = 43890
- 103 + 43787 = 43890
- 107 + 43783 = 43890
- 109 + 43781 = 43890
Showing the first eight; more decompositions exist.
