Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987204, here are decompositions:
- 5 + 987199 = 987204
- 11 + 987193 = 987204
- 13 + 987191 = 987204
- 61 + 987143 = 987204
- 103 + 987101 = 987204
- 107 + 987097 = 987204
- 137 + 987067 = 987204
- 151 + 987053 = 987204
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 987,204 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 987204 first appears in π at position 649,408 of the decimal expansion (the 649,408ordinal-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.
