Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135824, here are decompositions:
- 37 + 135787 = 135824
- 43 + 135781 = 135824
- 67 + 135757 = 135824
- 97 + 135727 = 135824
- 103 + 135721 = 135824
- 127 + 135697 = 135824
- 163 + 135661 = 135824
- 211 + 135613 = 135824
Showing the first eight; more decompositions exist.
