Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 922, here are decompositions:
- 3 + 919 = 922
- 11 + 911 = 922
- 41 + 881 = 922
- 59 + 863 = 922
- 83 + 839 = 922
- 101 + 821 = 922
- 113 + 809 = 922
- 149 + 773 = 922
Showing the first eight; more decompositions exist.
