Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183904, here are decompositions:
- 23 + 183881 = 183904
- 107 + 183797 = 183904
- 191 + 183713 = 183904
- 197 + 183707 = 183904
- 293 + 183611 = 183904
- 311 + 183593 = 183904
- 317 + 183587 = 183904
- 401 + 183503 = 183904
Showing the first eight; more decompositions exist.
