Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124872, here are decompositions:
- 19 + 124853 = 124872
- 53 + 124819 = 124872
- 73 + 124799 = 124872
- 79 + 124793 = 124872
- 89 + 124783 = 124872
- 101 + 124771 = 124872
- 103 + 124769 = 124872
- 113 + 124759 = 124872
Showing the first eight; more decompositions exist.
