Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139504, here are decompositions:
- 3 + 139501 = 139504
- 11 + 139493 = 139504
- 17 + 139487 = 139504
- 47 + 139457 = 139504
- 107 + 139397 = 139504
- 137 + 139367 = 139504
- 191 + 139313 = 139504
- 263 + 139241 = 139504
Showing the first eight; more decompositions exist.
