Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143738, here are decompositions:
- 19 + 143719 = 143738
- 61 + 143677 = 143738
- 109 + 143629 = 143738
- 211 + 143527 = 143738
- 229 + 143509 = 143738
- 271 + 143467 = 143738
- 277 + 143461 = 143738
- 337 + 143401 = 143738
Showing the first eight; more decompositions exist.
