Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126906, here are decompositions:
- 47 + 126859 = 126906
- 67 + 126839 = 126906
- 79 + 126827 = 126906
- 83 + 126823 = 126906
- 149 + 126757 = 126906
- 163 + 126743 = 126906
- 167 + 126739 = 126906
- 173 + 126733 = 126906
Showing the first eight; more decompositions exist.
