Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 50640, here are decompositions:
- 13 + 50627 = 50640
- 41 + 50599 = 50640
- 47 + 50593 = 50640
- 53 + 50587 = 50640
- 59 + 50581 = 50640
- 89 + 50551 = 50640
- 97 + 50543 = 50640
- 101 + 50539 = 50640
Showing the first eight; more decompositions exist.
