Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 436, here are decompositions:
- 3 + 433 = 436
- 5 + 431 = 436
- 17 + 419 = 436
- 47 + 389 = 436
- 53 + 383 = 436
- 83 + 353 = 436
- 89 + 347 = 436
- 167 + 269 = 436
Showing the first eight; more decompositions exist.
