Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57142, here are decompositions:
- 3 + 57139 = 57142
- 11 + 57131 = 57142
- 23 + 57119 = 57142
- 53 + 57089 = 57142
- 83 + 57059 = 57142
- 101 + 57041 = 57142
- 149 + 56993 = 57142
- 179 + 56963 = 57142
Showing the first eight; more decompositions exist.
