Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135270, here are decompositions:
- 13 + 135257 = 135270
- 29 + 135241 = 135270
- 59 + 135211 = 135270
- 61 + 135209 = 135270
- 73 + 135197 = 135270
- 89 + 135181 = 135270
- 97 + 135173 = 135270
- 139 + 135131 = 135270
Showing the first eight; more decompositions exist.
