Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144688, here are decompositions:
- 17 + 144671 = 144688
- 29 + 144659 = 144688
- 59 + 144629 = 144688
- 149 + 144539 = 144688
- 191 + 144497 = 144688
- 227 + 144461 = 144688
- 281 + 144407 = 144688
- 347 + 144341 = 144688
Showing the first eight; more decompositions exist.
