Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137646, here are decompositions:
- 7 + 137639 = 137646
- 13 + 137633 = 137646
- 23 + 137623 = 137646
- 53 + 137593 = 137646
- 59 + 137587 = 137646
- 73 + 137573 = 137646
- 79 + 137567 = 137646
- 109 + 137537 = 137646
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 137,646 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 137646 first appears in π at position 71,677 of the decimal expansion (the 71,677ordinal-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.
