Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105984, here are decompositions:
- 7 + 105977 = 105984
- 13 + 105971 = 105984
- 17 + 105967 = 105984
- 31 + 105953 = 105984
- 41 + 105943 = 105984
- 71 + 105913 = 105984
- 101 + 105883 = 105984
- 113 + 105871 = 105984
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 105,984 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 105984 first appears in π at position 483,464 of the decimal expansion (the 483,464ordinal-suffix:th 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.
