Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57130, here are decompositions:
- 11 + 57119 = 57130
- 23 + 57107 = 57130
- 41 + 57089 = 57130
- 53 + 57077 = 57130
- 71 + 57059 = 57130
- 83 + 57047 = 57130
- 89 + 57041 = 57130
- 131 + 56999 = 57130
Showing the first eight; more decompositions exist.
