Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18444, here are decompositions:
- 5 + 18439 = 18444
- 11 + 18433 = 18444
- 17 + 18427 = 18444
- 31 + 18413 = 18444
- 43 + 18401 = 18444
- 47 + 18397 = 18444
- 73 + 18371 = 18444
- 103 + 18341 = 18444
Showing the first eight; more decompositions exist.
