Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100988, here are decompositions:
- 7 + 100981 = 100988
- 31 + 100957 = 100988
- 61 + 100927 = 100988
- 241 + 100747 = 100988
- 367 + 100621 = 100988
- 379 + 100609 = 100988
- 397 + 100591 = 100988
- 439 + 100549 = 100988
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 100,988 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
