Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143786, here are decompositions:
- 7 + 143779 = 143786
- 43 + 143743 = 143786
- 67 + 143719 = 143786
- 109 + 143677 = 143786
- 157 + 143629 = 143786
- 193 + 143593 = 143786
- 277 + 143509 = 143786
- 283 + 143503 = 143786
Showing the first eight; more decompositions exist.
