Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22668, here are decompositions:
- 17 + 22651 = 22668
- 29 + 22639 = 22668
- 31 + 22637 = 22668
- 47 + 22621 = 22668
- 97 + 22571 = 22668
- 101 + 22567 = 22668
- 127 + 22541 = 22668
- 137 + 22531 = 22668
Showing the first eight; more decompositions exist.
