Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000780, here are decompositions:
- 3 + 1000777 = 1000780
- 17 + 1000763 = 1000780
- 59 + 1000721 = 1000780
- 83 + 1000697 = 1000780
- 89 + 1000691 = 1000780
- 101 + 1000679 = 1000780
- 113 + 1000667 = 1000780
- 191 + 1000589 = 1000780
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 1,000,780 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
