Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71218, here are decompositions:
- 47 + 71171 = 71218
- 71 + 71147 = 71218
- 89 + 71129 = 71218
- 137 + 71081 = 71218
- 149 + 71069 = 71218
- 179 + 71039 = 71218
- 227 + 70991 = 71218
- 239 + 70979 = 71218
Showing the first eight; more decompositions exist.
