Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10028, here are decompositions:
- 19 + 10009 = 10028
- 61 + 9967 = 10028
- 79 + 9949 = 10028
- 97 + 9931 = 10028
- 127 + 9901 = 10028
- 157 + 9871 = 10028
- 199 + 9829 = 10028
- 211 + 9817 = 10028
Showing the first eight; more decompositions exist.
