Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100520, here are decompositions:
- 3 + 100517 = 100520
- 19 + 100501 = 100520
- 37 + 100483 = 100520
- 61 + 100459 = 100520
- 73 + 100447 = 100520
- 103 + 100417 = 100520
- 109 + 100411 = 100520
- 127 + 100393 = 100520
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 100,520 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
