Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43438, here are decompositions:
- 11 + 43427 = 43438
- 41 + 43397 = 43438
- 47 + 43391 = 43438
- 107 + 43331 = 43438
- 167 + 43271 = 43438
- 389 + 43049 = 43438
- 401 + 43037 = 43438
- 419 + 43019 = 43438
Showing the first eight; more decompositions exist.
