Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100782, here are decompositions:
- 13 + 100769 = 100782
- 41 + 100741 = 100782
- 79 + 100703 = 100782
- 83 + 100699 = 100782
- 89 + 100693 = 100782
- 109 + 100673 = 100782
- 113 + 100669 = 100782
- 173 + 100609 = 100782
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 100,782 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
