Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43090, here are decompositions:
- 23 + 43067 = 43090
- 41 + 43049 = 43090
- 53 + 43037 = 43090
- 71 + 43019 = 43090
- 101 + 42989 = 43090
- 137 + 42953 = 43090
- 167 + 42923 = 43090
- 191 + 42899 = 43090
Showing the first eight; more decompositions exist.
