Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487764, here are decompositions:
- 7 + 487757 = 487764
- 23 + 487741 = 487764
- 31 + 487733 = 487764
- 37 + 487727 = 487764
- 47 + 487717 = 487764
- 61 + 487703 = 487764
- 73 + 487691 = 487764
- 83 + 487681 = 487764
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 487,764 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 487764 first appears in π at position 718,037 of the decimal expansion (the 718,037ordinal-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.
