Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85320, here are decompositions:
- 7 + 85313 = 85320
- 17 + 85303 = 85320
- 23 + 85297 = 85320
- 61 + 85259 = 85320
- 73 + 85247 = 85320
- 83 + 85237 = 85320
- 97 + 85223 = 85320
- 107 + 85213 = 85320
Showing the first eight; more decompositions exist.
