Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2946, here are decompositions:
- 7 + 2939 = 2946
- 19 + 2927 = 2946
- 29 + 2917 = 2946
- 37 + 2909 = 2946
- 43 + 2903 = 2946
- 59 + 2887 = 2946
- 67 + 2879 = 2946
- 89 + 2857 = 2946
Showing the first eight; more decompositions exist.
