Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2922, here are decompositions:
- 5 + 2917 = 2922
- 13 + 2909 = 2922
- 19 + 2903 = 2922
- 43 + 2879 = 2922
- 61 + 2861 = 2922
- 71 + 2851 = 2922
- 79 + 2843 = 2922
- 89 + 2833 = 2922
Showing the first eight; more decompositions exist.
