Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139590, here are decompositions:
- 19 + 139571 = 139590
- 43 + 139547 = 139590
- 53 + 139537 = 139590
- 79 + 139511 = 139590
- 89 + 139501 = 139590
- 97 + 139493 = 139590
- 103 + 139487 = 139590
- 107 + 139483 = 139590
Showing the first eight; more decompositions exist.
