Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40312, here are decompositions:
- 23 + 40289 = 40312
- 29 + 40283 = 40312
- 59 + 40253 = 40312
- 71 + 40241 = 40312
- 149 + 40163 = 40312
- 281 + 40031 = 40312
- 359 + 39953 = 40312
- 383 + 39929 = 40312
Showing the first eight; more decompositions exist.
