Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40446, here are decompositions:
- 13 + 40433 = 40446
- 17 + 40429 = 40446
- 19 + 40427 = 40446
- 23 + 40423 = 40446
- 59 + 40387 = 40446
- 89 + 40357 = 40446
- 103 + 40343 = 40446
- 157 + 40289 = 40446
Showing the first eight; more decompositions exist.
