Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2908, here are decompositions:
- 5 + 2903 = 2908
- 11 + 2897 = 2908
- 29 + 2879 = 2908
- 47 + 2861 = 2908
- 71 + 2837 = 2908
- 89 + 2819 = 2908
- 107 + 2801 = 2908
- 131 + 2777 = 2908
Showing the first eight; more decompositions exist.
