Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85204, here are decompositions:
- 3 + 85201 = 85204
- 5 + 85199 = 85204
- 11 + 85193 = 85204
- 71 + 85133 = 85204
- 83 + 85121 = 85204
- 101 + 85103 = 85204
- 113 + 85091 = 85204
- 167 + 85037 = 85204
Showing the first eight; more decompositions exist.
