Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139836, here are decompositions:
- 5 + 139831 = 139836
- 23 + 139813 = 139836
- 83 + 139753 = 139836
- 89 + 139747 = 139836
- 97 + 139739 = 139836
- 107 + 139729 = 139836
- 127 + 139709 = 139836
- 139 + 139697 = 139836
Showing the first eight; more decompositions exist.
