Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105590, here are decompositions:
- 61 + 105529 = 105590
- 73 + 105517 = 105590
- 193 + 105397 = 105590
- 211 + 105379 = 105590
- 223 + 105367 = 105590
- 229 + 105361 = 105590
- 271 + 105319 = 105590
- 313 + 105277 = 105590
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 105,590 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 105590 first appears in π at position 936,021 of the decimal expansion (the 936,021ordinal-suffix:st 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.
