Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120148, here are decompositions:
- 71 + 120077 = 120148
- 101 + 120047 = 120148
- 107 + 120041 = 120148
- 131 + 120017 = 120148
- 137 + 120011 = 120148
- 167 + 119981 = 120148
- 227 + 119921 = 120148
- 257 + 119891 = 120148
Showing the first eight; more decompositions exist.
