Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501664, here are decompositions:
- 5 + 501659 = 501664
- 41 + 501623 = 501664
- 47 + 501617 = 501664
- 71 + 501593 = 501664
- 101 + 501563 = 501664
- 263 + 501401 = 501664
- 281 + 501383 = 501664
- 347 + 501317 = 501664
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 501,664 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 501664 first appears in π at position 384,124 of the decimal expansion (the 384,124ordinal-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.
