Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53640, here are decompositions:
- 7 + 53633 = 53640
- 11 + 53629 = 53640
- 17 + 53623 = 53640
- 23 + 53617 = 53640
- 29 + 53611 = 53640
- 31 + 53609 = 53640
- 43 + 53597 = 53640
- 47 + 53593 = 53640
Showing the first eight; more decompositions exist.
