Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33440, here are decompositions:
- 13 + 33427 = 33440
- 31 + 33409 = 33440
- 37 + 33403 = 33440
- 97 + 33343 = 33440
- 109 + 33331 = 33440
- 139 + 33301 = 33440
- 151 + 33289 = 33440
- 193 + 33247 = 33440
Showing the first eight; more decompositions exist.
