Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187466, here are decompositions:
- 3 + 187463 = 187466
- 43 + 187423 = 187466
- 73 + 187393 = 187466
- 79 + 187387 = 187466
- 127 + 187339 = 187466
- 163 + 187303 = 187466
- 193 + 187273 = 187466
- 229 + 187237 = 187466
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 187,466 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 187466 first appears in π at position 608,510 of the decimal expansion (the 608,510ordinal-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.
