Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987608, here are decompositions:
- 67 + 987541 = 987608
- 151 + 987457 = 987608
- 397 + 987211 = 987608
- 409 + 987199 = 987608
- 541 + 987067 = 987608
- 547 + 987061 = 987608
- 619 + 986989 = 987608
- 751 + 986857 = 987608
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 987,608 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 987608 first appears in π at position 484,378 of the decimal expansion (the 484,378ordinal-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.
