Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144444, here are decompositions:
- 5 + 144439 = 144444
- 17 + 144427 = 144444
- 31 + 144413 = 144444
- 37 + 144407 = 144444
- 61 + 144383 = 144444
- 103 + 144341 = 144444
- 137 + 144307 = 144444
- 173 + 144271 = 144444
Showing the first eight; more decompositions exist.
