Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57200, here are decompositions:
- 7 + 57193 = 57200
- 37 + 57163 = 57200
- 61 + 57139 = 57200
- 103 + 57097 = 57200
- 127 + 57073 = 57200
- 163 + 57037 = 57200
- 211 + 56989 = 57200
- 271 + 56929 = 57200
Showing the first eight; more decompositions exist.
