Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987384, here are decompositions:
- 23 + 987361 = 987384
- 31 + 987353 = 987384
- 71 + 987313 = 987384
- 157 + 987227 = 987384
- 173 + 987211 = 987384
- 191 + 987193 = 987384
- 193 + 987191 = 987384
- 241 + 987143 = 987384
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 987,384 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 987384 first appears in π at position 948,301 of the decimal expansion (the 948,301ordinal-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.
