Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987704, here are decompositions:
- 7 + 987697 = 987704
- 73 + 987631 = 987704
- 97 + 987607 = 987704
- 163 + 987541 = 987704
- 181 + 987523 = 987704
- 241 + 987463 = 987704
- 271 + 987433 = 987704
- 313 + 987391 = 987704
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 987,704 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 987704 first appears in π at position 217,516 of the decimal expansion (the 217,516ordinal-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.
