Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487464, here are decompositions:
- 7 + 487457 = 487464
- 17 + 487447 = 487464
- 37 + 487427 = 487464
- 41 + 487423 = 487464
- 67 + 487397 = 487464
- 73 + 487391 = 487464
- 83 + 487381 = 487464
- 101 + 487363 = 487464
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 487,464 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 487464 first appears in π at position 70,091 of the decimal expansion (the 70,091ordinal-suffix:st 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.
