Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11920, here are decompositions:
- 11 + 11909 = 11920
- 17 + 11903 = 11920
- 23 + 11897 = 11920
- 53 + 11867 = 11920
- 89 + 11831 = 11920
- 107 + 11813 = 11920
- 113 + 11807 = 11920
- 131 + 11789 = 11920
Showing the first eight; more decompositions exist.
