Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85422, here are decompositions:
- 11 + 85411 = 85422
- 41 + 85381 = 85422
- 53 + 85369 = 85422
- 59 + 85363 = 85422
- 61 + 85361 = 85422
- 89 + 85333 = 85422
- 109 + 85313 = 85422
- 163 + 85259 = 85422
Showing the first eight; more decompositions exist.
