Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987422, here are decompositions:
- 31 + 987391 = 987422
- 61 + 987361 = 987422
- 109 + 987313 = 987422
- 211 + 987211 = 987422
- 223 + 987199 = 987422
- 229 + 987193 = 987422
- 379 + 987043 = 987422
- 409 + 987013 = 987422
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 987,422 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 987422 first appears in π at position 98,556 of the decimal expansion (the 98,556ordinal-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.
