Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143904, here are decompositions:
- 23 + 143881 = 143904
- 31 + 143873 = 143904
- 71 + 143833 = 143904
- 73 + 143831 = 143904
- 83 + 143821 = 143904
- 97 + 143807 = 143904
- 107 + 143797 = 143904
- 113 + 143791 = 143904
Showing the first eight; more decompositions exist.
