Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124686, here are decompositions:
- 7 + 124679 = 124686
- 13 + 124673 = 124686
- 17 + 124669 = 124686
- 43 + 124643 = 124686
- 53 + 124633 = 124686
- 109 + 124577 = 124686
- 157 + 124529 = 124686
- 173 + 124513 = 124686
Showing the first eight; more decompositions exist.
