Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138004, here are decompositions:
- 5 + 137999 = 138004
- 11 + 137993 = 138004
- 47 + 137957 = 138004
- 71 + 137933 = 138004
- 131 + 137873 = 138004
- 137 + 137867 = 138004
- 173 + 137831 = 138004
- 227 + 137777 = 138004
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 138,004 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 138004 first appears in π at position 820,848 of the decimal expansion (the 820,848ordinal-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.
