Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138604, here are decompositions:
- 5 + 138599 = 138604
- 17 + 138587 = 138604
- 23 + 138581 = 138604
- 41 + 138563 = 138604
- 107 + 138497 = 138604
- 197 + 138407 = 138604
- 233 + 138371 = 138604
- 281 + 138323 = 138604
Showing the first eight; more decompositions exist.
