Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139036, here are decompositions:
- 3 + 139033 = 139036
- 59 + 138977 = 139036
- 113 + 138923 = 139036
- 137 + 138899 = 139036
- 167 + 138869 = 139036
- 173 + 138863 = 139036
- 239 + 138797 = 139036
- 353 + 138683 = 139036
Showing the first eight; more decompositions exist.
