Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85124, here are decompositions:
- 3 + 85121 = 85124
- 31 + 85093 = 85124
- 37 + 85087 = 85124
- 43 + 85081 = 85124
- 97 + 85027 = 85124
- 103 + 85021 = 85124
- 157 + 84967 = 85124
- 163 + 84961 = 85124
Showing the first eight; more decompositions exist.
