Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100212, here are decompositions:
- 5 + 100207 = 100212
- 19 + 100193 = 100212
- 23 + 100189 = 100212
- 29 + 100183 = 100212
- 43 + 100169 = 100212
- 59 + 100153 = 100212
- 61 + 100151 = 100212
- 83 + 100129 = 100212
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 100,212 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
