Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987752, here are decompositions:
- 13 + 987739 = 987752
- 193 + 987559 = 987752
- 211 + 987541 = 987752
- 229 + 987523 = 987752
- 439 + 987313 = 987752
- 541 + 987211 = 987752
- 673 + 987079 = 987752
- 691 + 987061 = 987752
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 987,752 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 987752 first appears in π at position 468,723 of the decimal expansion (the 468,723ordinal-suffix:rd 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.
