Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84142, here are decompositions:
- 5 + 84137 = 84142
- 11 + 84131 = 84142
- 53 + 84089 = 84142
- 83 + 84059 = 84142
- 89 + 84053 = 84142
- 131 + 84011 = 84142
- 173 + 83969 = 84142
- 239 + 83903 = 84142
Showing the first eight; more decompositions exist.
