Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85112, here are decompositions:
- 3 + 85109 = 85112
- 19 + 85093 = 85112
- 31 + 85081 = 85112
- 103 + 85009 = 85112
- 151 + 84961 = 85112
- 193 + 84919 = 85112
- 199 + 84913 = 85112
- 241 + 84871 = 85112
Showing the first eight; more decompositions exist.
