Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28992, here are decompositions:
- 13 + 28979 = 28992
- 31 + 28961 = 28992
- 43 + 28949 = 28992
- 59 + 28933 = 28992
- 71 + 28921 = 28992
- 83 + 28909 = 28992
- 113 + 28879 = 28992
- 149 + 28843 = 28992
Showing the first eight; more decompositions exist.
