Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987342, here are decompositions:
- 29 + 987313 = 987342
- 43 + 987299 = 987342
- 131 + 987211 = 987342
- 149 + 987193 = 987342
- 151 + 987191 = 987342
- 199 + 987143 = 987342
- 241 + 987101 = 987342
- 263 + 987079 = 987342
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 987,342 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 987342 first appears in π at position 815,714 of the decimal expansion (the 815,714ordinal-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.
