Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009120, here are decompositions:
- 23 + 1009097 = 1009120
- 59 + 1009061 = 1009120
- 71 + 1009049 = 1009120
- 83 + 1009037 = 1009120
- 113 + 1009007 = 1009120
- 131 + 1008989 = 1009120
- 137 + 1008983 = 1009120
- 173 + 1008947 = 1009120
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 1,009,120 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
