Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101784, here are decompositions:
- 13 + 101771 = 101784
- 37 + 101747 = 101784
- 43 + 101741 = 101784
- 47 + 101737 = 101784
- 61 + 101723 = 101784
- 83 + 101701 = 101784
- 103 + 101681 = 101784
- 131 + 101653 = 101784
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 101,784 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
