Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987446, here are decompositions:
- 13 + 987433 = 987446
- 349 + 987097 = 987446
- 367 + 987079 = 987446
- 379 + 987067 = 987446
- 433 + 987013 = 987446
- 457 + 986989 = 987446
- 463 + 986983 = 987446
- 487 + 986959 = 987446
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 987,446 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 987446 first appears in π at position 82,654 of the decimal expansion (the 82,654ordinal-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.
