Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138696, here are decompositions:
- 13 + 138683 = 138696
- 17 + 138679 = 138696
- 59 + 138637 = 138696
- 67 + 138629 = 138696
- 79 + 138617 = 138696
- 97 + 138599 = 138696
- 109 + 138587 = 138696
- 127 + 138569 = 138696
Showing the first eight; more decompositions exist.
