Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143506, here are decompositions:
- 3 + 143503 = 143506
- 5 + 143501 = 143506
- 17 + 143489 = 143506
- 23 + 143483 = 143506
- 29 + 143477 = 143506
- 149 + 143357 = 143506
- 173 + 143333 = 143506
- 257 + 143249 = 143506
Showing the first eight; more decompositions exist.
