Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12148, here are decompositions:
- 5 + 12143 = 12148
- 29 + 12119 = 12148
- 41 + 12107 = 12148
- 47 + 12101 = 12148
- 107 + 12041 = 12148
- 137 + 12011 = 12148
- 167 + 11981 = 12148
- 179 + 11969 = 12148
Showing the first eight; more decompositions exist.
