Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16040, here are decompositions:
- 7 + 16033 = 16040
- 67 + 15973 = 16040
- 103 + 15937 = 16040
- 127 + 15913 = 16040
- 139 + 15901 = 16040
- 151 + 15889 = 16040
- 163 + 15877 = 16040
- 181 + 15859 = 16040
Showing the first eight; more decompositions exist.
