Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139132, here are decompositions:
- 11 + 139121 = 139132
- 23 + 139109 = 139132
- 41 + 139091 = 139132
- 53 + 139079 = 139132
- 173 + 138959 = 139132
- 233 + 138899 = 139132
- 239 + 138893 = 139132
- 263 + 138869 = 139132
Showing the first eight; more decompositions exist.
