Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130104, here are decompositions:
- 5 + 130099 = 130104
- 17 + 130087 = 130104
- 31 + 130073 = 130104
- 47 + 130057 = 130104
- 53 + 130051 = 130104
- 61 + 130043 = 130104
- 83 + 130021 = 130104
- 101 + 130003 = 130104
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 130,104 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 130104 first appears in π at position 127,824 of the decimal expansion (the 127,824ordinal-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.
