Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166248, here are decompositions:
- 11 + 166237 = 166248
- 29 + 166219 = 166248
- 41 + 166207 = 166248
- 59 + 166189 = 166248
- 79 + 166169 = 166248
- 97 + 166151 = 166248
- 101 + 166147 = 166248
- 149 + 166099 = 166248
Showing the first eight; more decompositions exist.
