Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 504840, here are decompositions:
- 19 + 504821 = 504840
- 23 + 504817 = 504840
- 41 + 504799 = 504840
- 43 + 504797 = 504840
- 53 + 504787 = 504840
- 73 + 504767 = 504840
- 113 + 504727 = 504840
- 157 + 504683 = 504840
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 504,840 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 504840 first appears in π at position 362,817 of the decimal expansion (the 362,817ordinal-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.
