Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32640, here are decompositions:
- 7 + 32633 = 32640
- 19 + 32621 = 32640
- 29 + 32611 = 32640
- 31 + 32609 = 32640
- 37 + 32603 = 32640
- 53 + 32587 = 32640
- 61 + 32579 = 32640
- 67 + 32573 = 32640
Showing the first eight; more decompositions exist.
