Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120144, here are decompositions:
- 23 + 120121 = 120144
- 41 + 120103 = 120144
- 47 + 120097 = 120144
- 53 + 120091 = 120144
- 67 + 120077 = 120144
- 97 + 120047 = 120144
- 103 + 120041 = 120144
- 127 + 120017 = 120144
Showing the first eight; more decompositions exist.
