Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139776, here are decompositions:
- 17 + 139759 = 139776
- 23 + 139753 = 139776
- 29 + 139747 = 139776
- 37 + 139739 = 139776
- 47 + 139729 = 139776
- 67 + 139709 = 139776
- 73 + 139703 = 139776
- 79 + 139697 = 139776
Showing the first eight; more decompositions exist.
