Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22780, here are decompositions:
- 3 + 22777 = 22780
- 11 + 22769 = 22780
- 29 + 22751 = 22780
- 41 + 22739 = 22780
- 53 + 22727 = 22780
- 59 + 22721 = 22780
- 71 + 22709 = 22780
- 83 + 22697 = 22780
Showing the first eight; more decompositions exist.
