Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71188, here are decompositions:
- 17 + 71171 = 71188
- 41 + 71147 = 71188
- 59 + 71129 = 71188
- 107 + 71081 = 71188
- 149 + 71039 = 71188
- 191 + 70997 = 71188
- 197 + 70991 = 71188
- 239 + 70949 = 71188
Showing the first eight; more decompositions exist.
