Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008000, here are decompositions:
- 23 + 1007977 = 1008000
- 29 + 1007971 = 1008000
- 41 + 1007959 = 1008000
- 43 + 1007957 = 1008000
- 61 + 1007939 = 1008000
- 67 + 1007933 = 1008000
- 79 + 1007921 = 1008000
- 109 + 1007891 = 1008000
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 1,008,000 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
