Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987328, here are decompositions:
- 29 + 987299 = 987328
- 101 + 987227 = 987328
- 137 + 987191 = 987328
- 227 + 987101 = 987328
- 239 + 987089 = 987328
- 347 + 986981 = 987328
- 401 + 986927 = 987328
- 479 + 986849 = 987328
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 987,328 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 987328 first appears in π at position 185,048 of the decimal expansion (the 185,048ordinal-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.
