Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181364, here are decompositions:
- 3 + 181361 = 181364
- 61 + 181303 = 181364
- 67 + 181297 = 181364
- 151 + 181213 = 181364
- 163 + 181201 = 181364
- 181 + 181183 = 181364
- 223 + 181141 = 181364
- 241 + 181123 = 181364
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 181,364 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 181364 first appears in π at position 766,487 of the decimal expansion (the 766,487ordinal-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.
