Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005998, here are decompositions:
- 61 + 1005937 = 1005998
- 67 + 1005931 = 1005998
- 337 + 1005661 = 1005998
- 379 + 1005619 = 1005998
- 457 + 1005541 = 1005998
- 541 + 1005457 = 1005998
- 571 + 1005427 = 1005998
- 607 + 1005391 = 1005998
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 1,005,998 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
