Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22782, here are decompositions:
- 5 + 22777 = 22782
- 13 + 22769 = 22782
- 31 + 22751 = 22782
- 41 + 22741 = 22782
- 43 + 22739 = 22782
- 61 + 22721 = 22782
- 73 + 22709 = 22782
- 83 + 22699 = 22782
Showing the first eight; more decompositions exist.
