Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137740, here are decompositions:
- 3 + 137737 = 137740
- 17 + 137723 = 137740
- 41 + 137699 = 137740
- 101 + 137639 = 137740
- 107 + 137633 = 137740
- 167 + 137573 = 137740
- 173 + 137567 = 137740
- 233 + 137507 = 137740
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 137,740 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 137740 first appears in π at position 231,738 of the decimal expansion (the 231,738ordinal-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.
