Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57180, here are decompositions:
- 7 + 57173 = 57180
- 17 + 57163 = 57180
- 31 + 57149 = 57180
- 37 + 57143 = 57180
- 41 + 57139 = 57180
- 61 + 57119 = 57180
- 73 + 57107 = 57180
- 83 + 57097 = 57180
Showing the first eight; more decompositions exist.
