Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157804, here are decompositions:
- 5 + 157799 = 157804
- 11 + 157793 = 157804
- 71 + 157733 = 157804
- 83 + 157721 = 157804
- 137 + 157667 = 157804
- 167 + 157637 = 157804
- 233 + 157571 = 157804
- 281 + 157523 = 157804
Showing the first eight; more decompositions exist.
