Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28058, here are decompositions:
- 7 + 28051 = 28058
- 31 + 28027 = 28058
- 61 + 27997 = 28058
- 97 + 27961 = 28058
- 139 + 27919 = 28058
- 157 + 27901 = 28058
- 211 + 27847 = 28058
- 241 + 27817 = 28058
Showing the first eight; more decompositions exist.
