Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139492, here are decompositions:
- 5 + 139487 = 139492
- 53 + 139439 = 139492
- 83 + 139409 = 139492
- 131 + 139361 = 139492
- 149 + 139343 = 139492
- 179 + 139313 = 139492
- 191 + 139301 = 139492
- 251 + 139241 = 139492
Showing the first eight; more decompositions exist.
