Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100202, here are decompositions:
- 13 + 100189 = 100202
- 19 + 100183 = 100202
- 73 + 100129 = 100202
- 199 + 100003 = 100202
- 211 + 99991 = 100202
- 241 + 99961 = 100202
- 331 + 99871 = 100202
- 373 + 99829 = 100202
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 100,202 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
