Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83918, here are decompositions:
- 7 + 83911 = 83918
- 61 + 83857 = 83918
- 127 + 83791 = 83918
- 157 + 83761 = 83918
- 181 + 83737 = 83918
- 199 + 83719 = 83918
- 229 + 83689 = 83918
- 277 + 83641 = 83918
Showing the first eight; more decompositions exist.
