Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183864, here are decompositions:
- 41 + 183823 = 183864
- 67 + 183797 = 183864
- 101 + 183763 = 183864
- 103 + 183761 = 183864
- 151 + 183713 = 183864
- 157 + 183707 = 183864
- 167 + 183697 = 183864
- 173 + 183691 = 183864
Showing the first eight; more decompositions exist.
