Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 504640, here are decompositions:
- 23 + 504617 = 504640
- 41 + 504599 = 504640
- 47 + 504593 = 504640
- 113 + 504527 = 504640
- 167 + 504473 = 504640
- 179 + 504461 = 504640
- 251 + 504389 = 504640
- 263 + 504377 = 504640
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 504,640 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 504640 first appears in π at position 712,835 of the decimal expansion (the 712,835ordinal-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.
