Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43138, here are decompositions:
- 5 + 43133 = 43138
- 71 + 43067 = 43138
- 89 + 43049 = 43138
- 101 + 43037 = 43138
- 149 + 42989 = 43138
- 239 + 42899 = 43138
- 317 + 42821 = 43138
- 401 + 42737 = 43138
Showing the first eight; more decompositions exist.
