Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135216, here are decompositions:
- 5 + 135211 = 135216
- 7 + 135209 = 135216
- 19 + 135197 = 135216
- 23 + 135193 = 135216
- 43 + 135173 = 135216
- 97 + 135119 = 135216
- 127 + 135089 = 135216
- 139 + 135077 = 135216
Showing the first eight; more decompositions exist.
