Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987112, here are decompositions:
- 11 + 987101 = 987112
- 23 + 987089 = 987112
- 29 + 987083 = 987112
- 59 + 987053 = 987112
- 83 + 987029 = 987112
- 89 + 987023 = 987112
- 131 + 986981 = 987112
- 149 + 986963 = 987112
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 987,112 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 987112 first appears in π at position 403,736 of the decimal expansion (the 403,736ordinal-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.
