Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105472, here are decompositions:
- 5 + 105467 = 105472
- 23 + 105449 = 105472
- 71 + 105401 = 105472
- 83 + 105389 = 105472
- 113 + 105359 = 105472
- 131 + 105341 = 105472
- 149 + 105323 = 105472
- 233 + 105239 = 105472
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 105,472 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 105472 first appears in π at position 769,163 of the decimal expansion (the 769,163ordinal-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.
