Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138592, here are decompositions:
- 5 + 138587 = 138592
- 11 + 138581 = 138592
- 23 + 138569 = 138592
- 29 + 138563 = 138592
- 131 + 138461 = 138592
- 191 + 138401 = 138592
- 269 + 138323 = 138592
- 281 + 138311 = 138592
Showing the first eight; more decompositions exist.
