Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987622, here are decompositions:
- 23 + 987599 = 987622
- 29 + 987593 = 987622
- 89 + 987533 = 987622
- 113 + 987509 = 987622
- 131 + 987491 = 987622
- 149 + 987473 = 987622
- 239 + 987383 = 987622
- 269 + 987353 = 987622
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 987,622 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 987622 first appears in π at position 235,007 of the decimal expansion (the 235,007ordinal-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.
