Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103858, here are decompositions:
- 17 + 103841 = 103858
- 47 + 103811 = 103858
- 71 + 103787 = 103858
- 89 + 103769 = 103858
- 239 + 103619 = 103858
- 281 + 103577 = 103858
- 347 + 103511 = 103858
- 401 + 103457 = 103858
Showing the first eight; more decompositions exist.
