Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139764, here are decompositions:
- 5 + 139759 = 139764
- 11 + 139753 = 139764
- 17 + 139747 = 139764
- 43 + 139721 = 139764
- 61 + 139703 = 139764
- 67 + 139697 = 139764
- 83 + 139681 = 139764
- 101 + 139663 = 139764
Showing the first eight; more decompositions exist.
