Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005750, here are decompositions:
- 41 + 1005709 = 1005750
- 71 + 1005679 = 1005750
- 73 + 1005677 = 1005750
- 89 + 1005661 = 1005750
- 103 + 1005647 = 1005750
- 107 + 1005643 = 1005750
- 113 + 1005637 = 1005750
- 131 + 1005619 = 1005750
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 1,005,750 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
