Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84020, here are decompositions:
- 3 + 84017 = 84020
- 37 + 83983 = 84020
- 109 + 83911 = 84020
- 151 + 83869 = 84020
- 163 + 83857 = 84020
- 229 + 83791 = 84020
- 283 + 83737 = 84020
- 331 + 83689 = 84020
Showing the first eight; more decompositions exist.
