Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71154, here are decompositions:
- 7 + 71147 = 71154
- 11 + 71143 = 71154
- 73 + 71081 = 71154
- 131 + 71023 = 71154
- 157 + 70997 = 71154
- 163 + 70991 = 71154
- 173 + 70981 = 71154
- 197 + 70957 = 71154
Showing the first eight; more decompositions exist.
