Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57138, here are decompositions:
- 7 + 57131 = 57138
- 19 + 57119 = 57138
- 31 + 57107 = 57138
- 41 + 57097 = 57138
- 61 + 57077 = 57138
- 79 + 57059 = 57138
- 97 + 57041 = 57138
- 101 + 57037 = 57138
Showing the first eight; more decompositions exist.
