Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85432, here are decompositions:
- 3 + 85429 = 85432
- 5 + 85427 = 85432
- 71 + 85361 = 85432
- 101 + 85331 = 85432
- 173 + 85259 = 85432
- 233 + 85199 = 85432
- 239 + 85193 = 85432
- 311 + 85121 = 85432
Showing the first eight; more decompositions exist.
