Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71918, here are decompositions:
- 19 + 71899 = 71918
- 31 + 71887 = 71918
- 37 + 71881 = 71918
- 97 + 71821 = 71918
- 109 + 71809 = 71918
- 157 + 71761 = 71918
- 199 + 71719 = 71918
- 211 + 71707 = 71918
Showing the first eight; more decompositions exist.
