Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40392, here are decompositions:
- 5 + 40387 = 40392
- 31 + 40361 = 40392
- 41 + 40351 = 40392
- 103 + 40289 = 40392
- 109 + 40283 = 40392
- 139 + 40253 = 40392
- 151 + 40241 = 40392
- 179 + 40213 = 40392
Showing the first eight; more decompositions exist.
