Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40120, here are decompositions:
- 83 + 40037 = 40120
- 89 + 40031 = 40120
- 107 + 40013 = 40120
- 131 + 39989 = 40120
- 137 + 39983 = 40120
- 149 + 39971 = 40120
- 167 + 39953 = 40120
- 191 + 39929 = 40120
Showing the first eight; more decompositions exist.
