Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135228, here are decompositions:
- 7 + 135221 = 135228
- 17 + 135211 = 135228
- 19 + 135209 = 135228
- 31 + 135197 = 135228
- 47 + 135181 = 135228
- 97 + 135131 = 135228
- 109 + 135119 = 135228
- 127 + 135101 = 135228
Showing the first eight; more decompositions exist.
