Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85444, here are decompositions:
- 5 + 85439 = 85444
- 17 + 85427 = 85444
- 83 + 85361 = 85444
- 113 + 85331 = 85444
- 131 + 85313 = 85444
- 197 + 85247 = 85444
- 251 + 85193 = 85444
- 311 + 85133 = 85444
Showing the first eight; more decompositions exist.
