Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183838, here are decompositions:
- 29 + 183809 = 183838
- 41 + 183797 = 183838
- 131 + 183707 = 183838
- 227 + 183611 = 183838
- 251 + 183587 = 183838
- 257 + 183581 = 183838
- 269 + 183569 = 183838
- 311 + 183527 = 183838
Showing the first eight; more decompositions exist.
