Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135178, here are decompositions:
- 5 + 135173 = 135178
- 47 + 135131 = 135178
- 59 + 135119 = 135178
- 89 + 135089 = 135178
- 101 + 135077 = 135178
- 149 + 135029 = 135178
- 179 + 134999 = 135178
- 227 + 134951 = 135178
Showing the first eight; more decompositions exist.
