Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987024, here are decompositions:
- 11 + 987013 = 987024
- 41 + 986983 = 987024
- 43 + 986981 = 987024
- 61 + 986963 = 987024
- 83 + 986941 = 987024
- 97 + 986927 = 987024
- 167 + 986857 = 987024
- 173 + 986851 = 987024
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 987,024 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 987024 first appears in π at position 202,217 of the decimal expansion (the 202,217ordinal-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.
