Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3028, here are decompositions:
- 5 + 3023 = 3028
- 17 + 3011 = 3028
- 29 + 2999 = 3028
- 59 + 2969 = 3028
- 71 + 2957 = 3028
- 89 + 2939 = 3028
- 101 + 2927 = 3028
- 131 + 2897 = 3028
Showing the first eight; more decompositions exist.
