Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85538, here are decompositions:
- 7 + 85531 = 85538
- 109 + 85429 = 85538
- 127 + 85411 = 85538
- 157 + 85381 = 85538
- 241 + 85297 = 85538
- 337 + 85201 = 85538
- 379 + 85159 = 85538
- 457 + 85081 = 85538
Showing the first eight; more decompositions exist.
