Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85120, here are decompositions:
- 11 + 85109 = 85120
- 17 + 85103 = 85120
- 29 + 85091 = 85120
- 59 + 85061 = 85120
- 71 + 85049 = 85120
- 83 + 85037 = 85120
- 173 + 84947 = 85120
- 251 + 84869 = 85120
Showing the first eight; more decompositions exist.
