Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144388, here are decompositions:
- 5 + 144383 = 144388
- 47 + 144341 = 144388
- 89 + 144299 = 144388
- 227 + 144161 = 144388
- 317 + 144071 = 144388
- 389 + 143999 = 144388
- 479 + 143909 = 144388
- 509 + 143879 = 144388
Showing the first eight; more decompositions exist.
