Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578664, here are decompositions:
- 5 + 578659 = 578664
- 17 + 578647 = 578664
- 43 + 578621 = 578664
- 61 + 578603 = 578664
- 67 + 578597 = 578664
- 83 + 578581 = 578664
- 101 + 578563 = 578664
- 127 + 578537 = 578664
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 578,664 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 578664 first appears in π at position 933,012 of the decimal expansion (the 933,012ordinal-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.
