Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85100, here are decompositions:
- 7 + 85093 = 85100
- 13 + 85087 = 85100
- 19 + 85081 = 85100
- 73 + 85027 = 85100
- 79 + 85021 = 85100
- 109 + 84991 = 85100
- 139 + 84961 = 85100
- 181 + 84919 = 85100
Showing the first eight; more decompositions exist.
