Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22740, here are decompositions:
- 13 + 22727 = 22740
- 19 + 22721 = 22740
- 23 + 22717 = 22740
- 31 + 22709 = 22740
- 41 + 22699 = 22740
- 43 + 22697 = 22740
- 61 + 22679 = 22740
- 71 + 22669 = 22740
Showing the first eight; more decompositions exist.
