Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85142, here are decompositions:
- 61 + 85081 = 85142
- 151 + 84991 = 85142
- 163 + 84979 = 85142
- 181 + 84961 = 85142
- 223 + 84919 = 85142
- 229 + 84913 = 85142
- 271 + 84871 = 85142
- 283 + 84859 = 85142
Showing the first eight; more decompositions exist.
