Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 412, here are decompositions:
- 3 + 409 = 412
- 11 + 401 = 412
- 23 + 389 = 412
- 29 + 383 = 412
- 53 + 359 = 412
- 59 + 353 = 412
- 101 + 311 = 412
- 131 + 281 = 412
Showing the first eight; more decompositions exist.
