Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124746, here are decompositions:
- 7 + 124739 = 124746
- 29 + 124717 = 124746
- 43 + 124703 = 124746
- 47 + 124699 = 124746
- 53 + 124693 = 124746
- 67 + 124679 = 124746
- 73 + 124673 = 124746
- 103 + 124643 = 124746
Showing the first eight; more decompositions exist.
