Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481624, here are decompositions:
- 5 + 481619 = 481624
- 47 + 481577 = 481624
- 53 + 481571 = 481624
- 191 + 481433 = 481624
- 251 + 481373 = 481624
- 281 + 481343 = 481624
- 317 + 481307 = 481624
- 443 + 481181 = 481624
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 481,624 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 481624 first appears in π at position 813,025 of the decimal expansion (the 813,025ordinal-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.
