Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704578, here are decompositions:
- 11 + 8704567 = 8704578
- 19 + 8704559 = 8704578
- 31 + 8704547 = 8704578
- 79 + 8704499 = 8704578
- 97 + 8704481 = 8704578
- 227 + 8704351 = 8704578
- 269 + 8704309 = 8704578
- 349 + 8704229 = 8704578
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 8,704,578 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 8704578 first appears in π at position 222,872 of the decimal expansion (the 222,872ordinal-suffix:nd 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.
