Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84140, here are decompositions:
- 3 + 84137 = 84140
- 13 + 84127 = 84140
- 19 + 84121 = 84140
- 73 + 84067 = 84140
- 79 + 84061 = 84140
- 157 + 83983 = 84140
- 229 + 83911 = 84140
- 271 + 83869 = 84140
Showing the first eight; more decompositions exist.
