Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100998, here are decompositions:
- 11 + 100987 = 100998
- 17 + 100981 = 100998
- 41 + 100957 = 100998
- 61 + 100937 = 100998
- 67 + 100931 = 100998
- 71 + 100927 = 100998
- 151 + 100847 = 100998
- 197 + 100801 = 100998
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 100,998 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
