Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137864, here are decompositions:
- 37 + 137827 = 137864
- 61 + 137803 = 137864
- 73 + 137791 = 137864
- 127 + 137737 = 137864
- 151 + 137713 = 137864
- 157 + 137707 = 137864
- 211 + 137653 = 137864
- 241 + 137623 = 137864
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 137,864 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 137864 first appears in π at position 577,295 of the decimal expansion (the 577,295ordinal-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.
