Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987454, here are decompositions:
- 71 + 987383 = 987454
- 101 + 987353 = 987454
- 227 + 987227 = 987454
- 263 + 987191 = 987454
- 311 + 987143 = 987454
- 353 + 987101 = 987454
- 401 + 987053 = 987454
- 431 + 987023 = 987454
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 987,454 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 987454 first appears in π at position 759,987 of the decimal expansion (the 759,987ordinal-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.
