Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2992, here are decompositions:
- 23 + 2969 = 2992
- 29 + 2963 = 2992
- 53 + 2939 = 2992
- 83 + 2909 = 2992
- 89 + 2903 = 2992
- 113 + 2879 = 2992
- 131 + 2861 = 2992
- 149 + 2843 = 2992
Showing the first eight; more decompositions exist.
