Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105730, here are decompositions:
- 3 + 105727 = 105730
- 29 + 105701 = 105730
- 47 + 105683 = 105730
- 167 + 105563 = 105730
- 173 + 105557 = 105730
- 197 + 105533 = 105730
- 227 + 105503 = 105730
- 239 + 105491 = 105730
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 105,730 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 105730 first appears in π at position 714,864 of the decimal expansion (the 714,864ordinal-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.
