Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84144, here are decompositions:
- 7 + 84137 = 84144
- 13 + 84131 = 84144
- 17 + 84127 = 84144
- 23 + 84121 = 84144
- 83 + 84061 = 84144
- 97 + 84047 = 84144
- 127 + 84017 = 84144
- 157 + 83987 = 84144
Showing the first eight; more decompositions exist.
