Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009800, here are decompositions:
- 13 + 1009787 = 1009800
- 19 + 1009781 = 1009800
- 53 + 1009747 = 1009800
- 59 + 1009741 = 1009800
- 73 + 1009727 = 1009800
- 131 + 1009669 = 1009800
- 149 + 1009651 = 1009800
- 151 + 1009649 = 1009800
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 1,009,800 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
