Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528864, here are decompositions:
- 31 + 528833 = 528864
- 41 + 528823 = 528864
- 43 + 528821 = 528864
- 53 + 528811 = 528864
- 73 + 528791 = 528864
- 101 + 528763 = 528864
- 157 + 528707 = 528864
- 173 + 528691 = 528864
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 528,864 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
