Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105456, here are decompositions:
- 7 + 105449 = 105456
- 19 + 105437 = 105456
- 59 + 105397 = 105456
- 67 + 105389 = 105456
- 83 + 105373 = 105456
- 89 + 105367 = 105456
- 97 + 105359 = 105456
- 137 + 105319 = 105456
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 105,456 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 105456 first appears in π at position 25,346 of the decimal expansion (the 25,346ordinal-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.
