Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143776, here are decompositions:
- 47 + 143729 = 143776
- 89 + 143687 = 143776
- 107 + 143669 = 143776
- 167 + 143609 = 143776
- 239 + 143537 = 143776
- 257 + 143519 = 143776
- 263 + 143513 = 143776
- 293 + 143483 = 143776
Showing the first eight; more decompositions exist.
