Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180104, here are decompositions:
- 7 + 180097 = 180104
- 31 + 180073 = 180104
- 61 + 180043 = 180104
- 97 + 180007 = 180104
- 103 + 180001 = 180104
- 151 + 179953 = 180104
- 157 + 179947 = 180104
- 181 + 179923 = 180104
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 180,104 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 180104 first appears in π at position 887,462 of the decimal expansion (the 887,462ordinal-suffix:nd 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.
