Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4864, here are decompositions:
- 3 + 4861 = 4864
- 47 + 4817 = 4864
- 71 + 4793 = 4864
- 113 + 4751 = 4864
- 131 + 4733 = 4864
- 173 + 4691 = 4864
- 191 + 4673 = 4864
- 227 + 4637 = 4864
Showing the first eight; more decompositions exist.
