Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105450, here are decompositions:
- 13 + 105437 = 105450
- 43 + 105407 = 105450
- 53 + 105397 = 105450
- 61 + 105389 = 105450
- 71 + 105379 = 105450
- 83 + 105367 = 105450
- 89 + 105361 = 105450
- 109 + 105341 = 105450
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 105,450 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 105450 first appears in π at position 330,304 of the decimal expansion (the 330,304ordinal-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.
