Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104540, here are decompositions:
- 3 + 104537 = 104540
- 13 + 104527 = 104540
- 61 + 104479 = 104540
- 67 + 104473 = 104540
- 157 + 104383 = 104540
- 193 + 104347 = 104540
- 229 + 104311 = 104540
- 307 + 104233 = 104540
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 104,540 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 104540 first appears in π at position 808,434 of the decimal expansion (the 808,434ordinal-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.
