Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000520, here are decompositions:
- 13 + 1000507 = 1000520
- 67 + 1000453 = 1000520
- 97 + 1000423 = 1000520
- 127 + 1000393 = 1000520
- 139 + 1000381 = 1000520
- 163 + 1000357 = 1000520
- 229 + 1000291 = 1000520
- 271 + 1000249 = 1000520
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 1,000,520 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
