Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2896, here are decompositions:
- 17 + 2879 = 2896
- 53 + 2843 = 2896
- 59 + 2837 = 2896
- 107 + 2789 = 2896
- 167 + 2729 = 2896
- 197 + 2699 = 2896
- 233 + 2663 = 2896
- 239 + 2657 = 2896
Showing the first eight; more decompositions exist.
