Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84080, here are decompositions:
- 13 + 84067 = 84080
- 19 + 84061 = 84080
- 97 + 83983 = 84080
- 211 + 83869 = 84080
- 223 + 83857 = 84080
- 307 + 83773 = 84080
- 379 + 83701 = 84080
- 439 + 83641 = 84080
Showing the first eight; more decompositions exist.
