Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163560, here are decompositions:
- 17 + 163543 = 163560
- 43 + 163517 = 163560
- 73 + 163487 = 163560
- 79 + 163481 = 163560
- 83 + 163477 = 163560
- 127 + 163433 = 163560
- 149 + 163411 = 163560
- 151 + 163409 = 163560
Showing the first eight; more decompositions exist.
