Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39540, here are decompositions:
- 19 + 39521 = 39540
- 29 + 39511 = 39540
- 31 + 39509 = 39540
- 37 + 39503 = 39540
- 41 + 39499 = 39540
- 79 + 39461 = 39540
- 89 + 39451 = 39540
- 97 + 39443 = 39540
Showing the first eight; more decompositions exist.
