Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84188, here are decompositions:
- 7 + 84181 = 84188
- 61 + 84127 = 84188
- 67 + 84121 = 84188
- 127 + 84061 = 84188
- 277 + 83911 = 84188
- 331 + 83857 = 84188
- 397 + 83791 = 84188
- 487 + 83701 = 84188
Showing the first eight; more decompositions exist.
