Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71278, here are decompositions:
- 17 + 71261 = 71278
- 29 + 71249 = 71278
- 41 + 71237 = 71278
- 107 + 71171 = 71278
- 131 + 71147 = 71278
- 149 + 71129 = 71278
- 197 + 71081 = 71278
- 239 + 71039 = 71278
Showing the first eight; more decompositions exist.
