Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138064, here are decompositions:
- 5 + 138059 = 138064
- 11 + 138053 = 138064
- 23 + 138041 = 138064
- 71 + 137993 = 138064
- 107 + 137957 = 138064
- 131 + 137933 = 138064
- 137 + 137927 = 138064
- 191 + 137873 = 138064
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 138,064 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 138064 first appears in π at position 236,740 of the decimal expansion (the 236,740ordinal-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.
