Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143856, here are decompositions:
- 23 + 143833 = 143856
- 29 + 143827 = 143856
- 43 + 143813 = 143856
- 59 + 143797 = 143856
- 113 + 143743 = 143856
- 127 + 143729 = 143856
- 137 + 143719 = 143856
- 157 + 143699 = 143856
Showing the first eight; more decompositions exist.
