Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22644, here are decompositions:
- 5 + 22639 = 22644
- 7 + 22637 = 22644
- 23 + 22621 = 22644
- 31 + 22613 = 22644
- 71 + 22573 = 22644
- 73 + 22571 = 22644
- 101 + 22543 = 22644
- 103 + 22541 = 22644
Showing the first eight; more decompositions exist.
