Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143752, here are decompositions:
- 23 + 143729 = 143752
- 41 + 143711 = 143752
- 53 + 143699 = 143752
- 83 + 143669 = 143752
- 101 + 143651 = 143752
- 179 + 143573 = 143752
- 233 + 143519 = 143752
- 239 + 143513 = 143752
Showing the first eight; more decompositions exist.
