Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009400, here are decompositions:
- 13 + 1009387 = 1009400
- 31 + 1009369 = 1009400
- 43 + 1009357 = 1009400
- 79 + 1009321 = 1009400
- 97 + 1009303 = 1009400
- 109 + 1009291 = 1009400
- 157 + 1009243 = 1009400
- 163 + 1009237 = 1009400
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 1,009,400 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
