Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104580, here are decompositions:
- 19 + 104561 = 104580
- 29 + 104551 = 104580
- 31 + 104549 = 104580
- 37 + 104543 = 104580
- 43 + 104537 = 104580
- 53 + 104527 = 104580
- 67 + 104513 = 104580
- 89 + 104491 = 104580
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 104,580 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 104580 first appears in π at position 104,138 of the decimal expansion (the 104,138ordinal-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.
