Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581704, here are decompositions:
- 3 + 581701 = 581704
- 5 + 581699 = 581704
- 17 + 581687 = 581704
- 41 + 581663 = 581704
- 47 + 581657 = 581704
- 107 + 581597 = 581704
- 131 + 581573 = 581704
- 257 + 581447 = 581704
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 581,704 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 581704 first appears in π at position 204,586 of the decimal expansion (the 204,586ordinal-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.
