Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100506, here are decompositions:
- 5 + 100501 = 100506
- 13 + 100493 = 100506
- 23 + 100483 = 100506
- 37 + 100469 = 100506
- 47 + 100459 = 100506
- 59 + 100447 = 100506
- 89 + 100417 = 100506
- 103 + 100403 = 100506
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 100,506 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
