Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40156, here are decompositions:
- 3 + 40153 = 40156
- 5 + 40151 = 40156
- 29 + 40127 = 40156
- 167 + 39989 = 40156
- 173 + 39983 = 40156
- 227 + 39929 = 40156
- 269 + 39887 = 40156
- 293 + 39863 = 40156
Showing the first eight; more decompositions exist.
