Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2928, here are decompositions:
- 11 + 2917 = 2928
- 19 + 2909 = 2928
- 31 + 2897 = 2928
- 41 + 2887 = 2928
- 67 + 2861 = 2928
- 71 + 2857 = 2928
- 109 + 2819 = 2928
- 127 + 2801 = 2928
Showing the first eight; more decompositions exist.
