Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163784, here are decompositions:
- 3 + 163781 = 163784
- 13 + 163771 = 163784
- 31 + 163753 = 163784
- 43 + 163741 = 163784
- 151 + 163633 = 163784
- 157 + 163627 = 163784
- 163 + 163621 = 163784
- 211 + 163573 = 163784
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 163,784 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163784 first appears in π at position 274,203 of the decimal expansion (the 274,203ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
