Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84218, here are decompositions:
- 7 + 84211 = 84218
- 19 + 84199 = 84218
- 37 + 84181 = 84218
- 97 + 84121 = 84218
- 151 + 84067 = 84218
- 157 + 84061 = 84218
- 307 + 83911 = 84218
- 349 + 83869 = 84218
Showing the first eight; more decompositions exist.
