Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57156, here are decompositions:
- 7 + 57149 = 57156
- 13 + 57143 = 57156
- 17 + 57139 = 57156
- 37 + 57119 = 57156
- 59 + 57097 = 57156
- 67 + 57089 = 57156
- 79 + 57077 = 57156
- 83 + 57073 = 57156
Showing the first eight; more decompositions exist.
