Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124858, here are decompositions:
- 5 + 124853 = 124858
- 11 + 124847 = 124858
- 59 + 124799 = 124858
- 89 + 124769 = 124858
- 137 + 124721 = 124858
- 179 + 124679 = 124858
- 257 + 124601 = 124858
- 281 + 124577 = 124858
Showing the first eight; more decompositions exist.
