Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9128, here are decompositions:
- 19 + 9109 = 9128
- 37 + 9091 = 9128
- 61 + 9067 = 9128
- 79 + 9049 = 9128
- 127 + 9001 = 9128
- 157 + 8971 = 9128
- 199 + 8929 = 9128
- 241 + 8887 = 9128
Showing the first eight; more decompositions exist.
