Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135678, here are decompositions:
- 7 + 135671 = 135678
- 17 + 135661 = 135678
- 29 + 135649 = 135678
- 31 + 135647 = 135678
- 41 + 135637 = 135678
- 61 + 135617 = 135678
- 71 + 135607 = 135678
- 79 + 135599 = 135678
Showing the first eight; more decompositions exist.
