Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142104, here are decompositions:
- 5 + 142099 = 142104
- 7 + 142097 = 142104
- 37 + 142067 = 142104
- 43 + 142061 = 142104
- 47 + 142057 = 142104
- 73 + 142031 = 142104
- 97 + 142007 = 142104
- 113 + 141991 = 142104
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 142,104 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 142104 first appears in π at position 205,176 of the decimal expansion (the 205,176ordinal-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.
