Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7028, here are decompositions:
- 31 + 6997 = 7028
- 37 + 6991 = 7028
- 61 + 6967 = 7028
- 67 + 6961 = 7028
- 79 + 6949 = 7028
- 157 + 6871 = 7028
- 199 + 6829 = 7028
- 337 + 6691 = 7028
Showing the first eight; more decompositions exist.
