Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85570, here are decompositions:
- 47 + 85523 = 85570
- 53 + 85517 = 85570
- 83 + 85487 = 85570
- 101 + 85469 = 85570
- 131 + 85439 = 85570
- 239 + 85331 = 85570
- 257 + 85313 = 85570
- 311 + 85259 = 85570
Showing the first eight; more decompositions exist.
