Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32144, here are decompositions:
- 3 + 32141 = 32144
- 61 + 32083 = 32144
- 67 + 32077 = 32144
- 163 + 31981 = 32144
- 181 + 31963 = 32144
- 271 + 31873 = 32144
- 373 + 31771 = 32144
- 421 + 31723 = 32144
Showing the first eight; more decompositions exist.
