Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85540, here are decompositions:
- 17 + 85523 = 85540
- 23 + 85517 = 85540
- 53 + 85487 = 85540
- 71 + 85469 = 85540
- 89 + 85451 = 85540
- 101 + 85439 = 85540
- 113 + 85427 = 85540
- 179 + 85361 = 85540
Showing the first eight; more decompositions exist.
