Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124188, here are decompositions:
- 5 + 124183 = 124188
- 7 + 124181 = 124188
- 17 + 124171 = 124188
- 41 + 124147 = 124188
- 67 + 124121 = 124188
- 101 + 124087 = 124188
- 167 + 124021 = 124188
- 191 + 123997 = 124188
Showing the first eight; more decompositions exist.
