Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100402, here are decompositions:
- 11 + 100391 = 100402
- 23 + 100379 = 100402
- 41 + 100361 = 100402
- 59 + 100343 = 100402
- 89 + 100313 = 100402
- 131 + 100271 = 100402
- 233 + 100169 = 100402
- 251 + 100151 = 100402
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 100,402 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
