Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163488, here are decompositions:
- 5 + 163483 = 163488
- 7 + 163481 = 163488
- 11 + 163477 = 163488
- 19 + 163469 = 163488
- 71 + 163417 = 163488
- 79 + 163409 = 163488
- 137 + 163351 = 163488
- 151 + 163337 = 163488
Showing the first eight; more decompositions exist.
