Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137684, here are decompositions:
- 31 + 137653 = 137684
- 61 + 137623 = 137684
- 97 + 137587 = 137684
- 193 + 137491 = 137684
- 241 + 137443 = 137684
- 271 + 137413 = 137684
- 331 + 137353 = 137684
- 433 + 137251 = 137684
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 137,684 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 137684 first appears in π at position 471,348 of the decimal expansion (the 471,348ordinal-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.
