Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987464, here are decompositions:
- 7 + 987457 = 987464
- 31 + 987433 = 987464
- 73 + 987391 = 987464
- 103 + 987361 = 987464
- 151 + 987313 = 987464
- 271 + 987193 = 987464
- 337 + 987127 = 987464
- 367 + 987097 = 987464
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 987,464 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 987464 first appears in π at position 169,941 of the decimal expansion (the 169,941ordinal-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.
