Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126108, here are decompositions:
- 11 + 126097 = 126108
- 29 + 126079 = 126108
- 41 + 126067 = 126108
- 61 + 126047 = 126108
- 67 + 126041 = 126108
- 71 + 126037 = 126108
- 89 + 126019 = 126108
- 97 + 126011 = 126108
Showing the first eight; more decompositions exist.
