Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139306, here are decompositions:
- 3 + 139303 = 139306
- 5 + 139301 = 139306
- 107 + 139199 = 139306
- 137 + 139169 = 139306
- 173 + 139133 = 139306
- 197 + 139109 = 139306
- 227 + 139079 = 139306
- 239 + 139067 = 139306
Showing the first eight; more decompositions exist.
