Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704584, here are decompositions:
- 17 + 8704567 = 8704584
- 37 + 8704547 = 8704584
- 61 + 8704523 = 8704584
- 71 + 8704513 = 8704584
- 103 + 8704481 = 8704584
- 151 + 8704433 = 8704584
- 167 + 8704417 = 8704584
- 181 + 8704403 = 8704584
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 8,704,584 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8704584 first appears in π at position 102,840 of the decimal expansion (the 102,840ordinal-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.
