Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4858, here are decompositions:
- 41 + 4817 = 4858
- 59 + 4799 = 4858
- 71 + 4787 = 4858
- 107 + 4751 = 4858
- 137 + 4721 = 4858
- 167 + 4691 = 4858
- 179 + 4679 = 4858
- 311 + 4547 = 4858
Showing the first eight; more decompositions exist.
