Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71208, here are decompositions:
- 17 + 71191 = 71208
- 37 + 71171 = 71208
- 41 + 71167 = 71208
- 47 + 71161 = 71208
- 61 + 71147 = 71208
- 79 + 71129 = 71208
- 89 + 71119 = 71208
- 127 + 71081 = 71208
Showing the first eight; more decompositions exist.
