Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85020, here are decompositions:
- 11 + 85009 = 85020
- 29 + 84991 = 85020
- 41 + 84979 = 85020
- 43 + 84977 = 85020
- 53 + 84967 = 85020
- 59 + 84961 = 85020
- 73 + 84947 = 85020
- 101 + 84919 = 85020
Showing the first eight; more decompositions exist.
