Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139598, here are decompositions:
- 7 + 139591 = 139598
- 61 + 139537 = 139598
- 97 + 139501 = 139598
- 139 + 139459 = 139598
- 211 + 139387 = 139598
- 229 + 139369 = 139598
- 307 + 139291 = 139598
- 331 + 139267 = 139598
Showing the first eight; more decompositions exist.
