Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124806, here are decompositions:
- 7 + 124799 = 124806
- 13 + 124793 = 124806
- 23 + 124783 = 124806
- 29 + 124777 = 124806
- 37 + 124769 = 124806
- 47 + 124759 = 124806
- 53 + 124753 = 124806
- 67 + 124739 = 124806
Showing the first eight; more decompositions exist.
