Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126216, here are decompositions:
- 5 + 126211 = 126216
- 17 + 126199 = 126216
- 43 + 126173 = 126216
- 73 + 126143 = 126216
- 89 + 126127 = 126216
- 109 + 126107 = 126216
- 137 + 126079 = 126216
- 149 + 126067 = 126216
Showing the first eight; more decompositions exist.
