Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101998, here are decompositions:
- 11 + 101987 = 101998
- 41 + 101957 = 101998
- 59 + 101939 = 101998
- 107 + 101891 = 101998
- 191 + 101807 = 101998
- 227 + 101771 = 101998
- 251 + 101747 = 101998
- 257 + 101741 = 101998
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 101,998 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
