Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163804, here are decompositions:
- 23 + 163781 = 163804
- 71 + 163733 = 163804
- 107 + 163697 = 163804
- 131 + 163673 = 163804
- 167 + 163637 = 163804
- 191 + 163613 = 163804
- 317 + 163487 = 163804
- 401 + 163403 = 163804
Showing the first eight; more decompositions exist.
