Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135888, here are decompositions:
- 29 + 135859 = 135888
- 37 + 135851 = 135888
- 47 + 135841 = 135888
- 59 + 135829 = 135888
- 89 + 135799 = 135888
- 101 + 135787 = 135888
- 107 + 135781 = 135888
- 131 + 135757 = 135888
Showing the first eight; more decompositions exist.
