Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2936, here are decompositions:
- 19 + 2917 = 2936
- 79 + 2857 = 2936
- 103 + 2833 = 2936
- 139 + 2797 = 2936
- 223 + 2713 = 2936
- 229 + 2707 = 2936
- 277 + 2659 = 2936
- 379 + 2557 = 2936
Showing the first eight; more decompositions exist.
