Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10128, here are decompositions:
- 17 + 10111 = 10128
- 29 + 10099 = 10128
- 37 + 10091 = 10128
- 59 + 10069 = 10128
- 61 + 10067 = 10128
- 67 + 10061 = 10128
- 89 + 10039 = 10128
- 179 + 9949 = 10128
Showing the first eight; more decompositions exist.
