Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 444, here are decompositions:
- 5 + 439 = 444
- 11 + 433 = 444
- 13 + 431 = 444
- 23 + 421 = 444
- 43 + 401 = 444
- 47 + 397 = 444
- 61 + 383 = 444
- 71 + 373 = 444
Showing the first eight; more decompositions exist.
