Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139616, here are decompositions:
- 7 + 139609 = 139616
- 19 + 139597 = 139616
- 79 + 139537 = 139616
- 157 + 139459 = 139616
- 193 + 139423 = 139616
- 223 + 139393 = 139616
- 229 + 139387 = 139616
- 277 + 139339 = 139616
Showing the first eight; more decompositions exist.
