Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180504, here are decompositions:
- 7 + 180497 = 180504
- 13 + 180491 = 180504
- 31 + 180473 = 180504
- 41 + 180463 = 180504
- 67 + 180437 = 180504
- 113 + 180391 = 180504
- 157 + 180347 = 180504
- 167 + 180337 = 180504
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 180,504 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 180504 first appears in π at position 297,551 of the decimal expansion (the 297,551ordinal-suffix:st 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.
