Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138682, here are decompositions:
- 3 + 138679 = 138682
- 41 + 138641 = 138682
- 53 + 138629 = 138682
- 83 + 138599 = 138682
- 101 + 138581 = 138682
- 113 + 138569 = 138682
- 233 + 138449 = 138682
- 281 + 138401 = 138682
Showing the first eight; more decompositions exist.
