Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138246, here are decompositions:
- 5 + 138241 = 138246
- 7 + 138239 = 138246
- 37 + 138209 = 138246
- 67 + 138179 = 138246
- 83 + 138163 = 138246
- 89 + 138157 = 138246
- 103 + 138143 = 138246
- 107 + 138139 = 138246
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 138,246 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 138246 first appears in π at position 267,914 of the decimal expansion (the 267,914ordinal-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.
