Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85420, here are decompositions:
- 59 + 85361 = 85420
- 89 + 85331 = 85420
- 107 + 85313 = 85420
- 173 + 85247 = 85420
- 191 + 85229 = 85420
- 197 + 85223 = 85420
- 227 + 85193 = 85420
- 311 + 85109 = 85420
Showing the first eight; more decompositions exist.
