Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987482, here are decompositions:
- 19 + 987463 = 987482
- 271 + 987211 = 987482
- 283 + 987199 = 987482
- 421 + 987061 = 987482
- 439 + 987043 = 987482
- 499 + 986983 = 987482
- 523 + 986959 = 987482
- 541 + 986941 = 987482
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 987,482 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 987482 first appears in π at position 401,317 of the decimal expansion (the 401,317ordinal-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.
