Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143656, here are decompositions:
- 3 + 143653 = 143656
- 5 + 143651 = 143656
- 47 + 143609 = 143656
- 83 + 143573 = 143656
- 89 + 143567 = 143656
- 137 + 143519 = 143656
- 167 + 143489 = 143656
- 173 + 143483 = 143656
Showing the first eight; more decompositions exist.
