Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100920, here are decompositions:
- 7 + 100913 = 100920
- 13 + 100907 = 100920
- 67 + 100853 = 100920
- 73 + 100847 = 100920
- 97 + 100823 = 100920
- 109 + 100811 = 100920
- 151 + 100769 = 100920
- 173 + 100747 = 100920
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 100,920 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
