Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85138, here are decompositions:
- 5 + 85133 = 85138
- 17 + 85121 = 85138
- 29 + 85109 = 85138
- 47 + 85091 = 85138
- 89 + 85049 = 85138
- 101 + 85037 = 85138
- 191 + 84947 = 85138
- 269 + 84869 = 85138
Showing the first eight; more decompositions exist.
