Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83870, here are decompositions:
- 13 + 83857 = 83870
- 37 + 83833 = 83870
- 79 + 83791 = 83870
- 97 + 83773 = 83870
- 109 + 83761 = 83870
- 151 + 83719 = 83870
- 181 + 83689 = 83870
- 229 + 83641 = 83870
Showing the first eight; more decompositions exist.
