Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82918, here are decompositions:
- 5 + 82913 = 82918
- 29 + 82889 = 82918
- 71 + 82847 = 82918
- 107 + 82811 = 82918
- 131 + 82787 = 82918
- 137 + 82781 = 82918
- 191 + 82727 = 82918
- 197 + 82721 = 82918
Showing the first eight; more decompositions exist.
