Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84440, here are decompositions:
- 3 + 84437 = 84440
- 19 + 84421 = 84440
- 127 + 84313 = 84440
- 193 + 84247 = 84440
- 211 + 84229 = 84440
- 229 + 84211 = 84440
- 241 + 84199 = 84440
- 277 + 84163 = 84440
Showing the first eight; more decompositions exist.
