Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2852, here are decompositions:
- 19 + 2833 = 2852
- 61 + 2791 = 2852
- 103 + 2749 = 2852
- 139 + 2713 = 2852
- 163 + 2689 = 2852
- 181 + 2671 = 2852
- 193 + 2659 = 2852
- 313 + 2539 = 2852
Showing the first eight; more decompositions exist.
