Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7208, here are decompositions:
- 31 + 7177 = 7208
- 79 + 7129 = 7208
- 139 + 7069 = 7208
- 151 + 7057 = 7208
- 181 + 7027 = 7208
- 211 + 6997 = 7208
- 241 + 6967 = 7208
- 337 + 6871 = 7208
Showing the first eight; more decompositions exist.
