Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126168, here are decompositions:
- 17 + 126151 = 126168
- 37 + 126131 = 126168
- 41 + 126127 = 126168
- 61 + 126107 = 126168
- 71 + 126097 = 126168
- 89 + 126079 = 126168
- 101 + 126067 = 126168
- 127 + 126041 = 126168
Showing the first eight; more decompositions exist.
