Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85402, here are decompositions:
- 41 + 85361 = 85402
- 71 + 85331 = 85402
- 89 + 85313 = 85402
- 173 + 85229 = 85402
- 179 + 85223 = 85402
- 269 + 85133 = 85402
- 281 + 85121 = 85402
- 293 + 85109 = 85402
Showing the first eight; more decompositions exist.
