Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138652, here are decompositions:
- 5 + 138647 = 138652
- 11 + 138641 = 138652
- 23 + 138629 = 138652
- 53 + 138599 = 138652
- 71 + 138581 = 138652
- 83 + 138569 = 138652
- 89 + 138563 = 138652
- 191 + 138461 = 138652
Showing the first eight; more decompositions exist.
