Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66148, here are decompositions:
- 11 + 66137 = 66148
- 41 + 66107 = 66148
- 59 + 66089 = 66148
- 101 + 66047 = 66148
- 107 + 66041 = 66148
- 167 + 65981 = 66148
- 191 + 65957 = 66148
- 197 + 65951 = 66148
Showing the first eight; more decompositions exist.
