Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139480, here are decompositions:
- 23 + 139457 = 139480
- 41 + 139439 = 139480
- 71 + 139409 = 139480
- 83 + 139397 = 139480
- 113 + 139367 = 139480
- 137 + 139343 = 139480
- 167 + 139313 = 139480
- 179 + 139301 = 139480
Showing the first eight; more decompositions exist.
