Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144448, here are decompositions:
- 41 + 144407 = 144448
- 107 + 144341 = 144448
- 137 + 144311 = 144448
- 149 + 144299 = 144448
- 281 + 144167 = 144448
- 449 + 143999 = 144448
- 467 + 143981 = 144448
- 569 + 143879 = 144448
Showing the first eight; more decompositions exist.
