Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143804, here are decompositions:
- 7 + 143797 = 143804
- 13 + 143791 = 143804
- 61 + 143743 = 143804
- 127 + 143677 = 143804
- 151 + 143653 = 143804
- 211 + 143593 = 143804
- 277 + 143527 = 143804
- 337 + 143467 = 143804
Showing the first eight; more decompositions exist.
