Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143894, here are decompositions:
- 13 + 143881 = 143894
- 61 + 143833 = 143894
- 67 + 143827 = 143894
- 73 + 143821 = 143894
- 97 + 143797 = 143894
- 103 + 143791 = 143894
- 151 + 143743 = 143894
- 241 + 143653 = 143894
Showing the first eight; more decompositions exist.
